Research output is disseminated primarily as refereed journal articles as well as articles in conference proceedings. The expertise available at the institute is organized below according to the areas of specialization. % \vspace{-5.0mm} \subsubsection{Mathematics} \vspace{-4.0mm} % The Mathematics group has wide ranging interests. These specializations are conveniently grouped together under broad headings. A very brief description is provided followed by the names of faculty members currently working in these areas. In 2008-2009, a total of 59 articles were submitted/accepted/published in journals and conference proceedings. %conference proceedings. \vspace{-1.0mm} \begin{itemize} \item{\bf Algebra:} % Algebra is the study of the properties of mathematical structures involving ``algebraic'' operations such as addition and multiplication. One of the main motivations to study algebraic structures is to analyze geometric objects such as curves and surfaces via the algebra of functions defined on them. Aspects of algebra being studied at IMSc involve algebraic geometry (study of loci of solutions of polynomial equations), algebraic groups (groups of matrices), and the theory of knots. \newline % [{\small{\bf Vijay Kodiyalam, D. S. Nagaraj, K. N. Raghavan.}}]\newline % \item{\bf Algebraic Geometry:} % This branch of mathematics is a study of the solution set of a finite set of polynomials in several variables. The total degrees of the polynomials and the number of polynomials play an important role in determining the geometry of the solution set. This subject has rich interactions with mathematical physics and other areas.\newline % [{\small{\bf Jaya Iyer, Kapil Paranjape, D. S. Nagaraj}}]\newline % \item{\bf Mathematical physics:} % An important area of mathematical physics is the spectral theory of Schr\"odinger operators. Such operators arise in describing the quantum mechanics of particles. The spectrum of such an operator gives the possible energies of the quantum system. The operators are considered both for deterministic as well as random potentials and the focus is on obtaining the spectrum rigorously. \newline Another area of study is the quantum spin chains, where the ground state of various models is studied for its uniqueness. Another major question in the area is the existence of a mass gap. In addition to these entropy of quantum dynamical systems is studied.\newline % [{\small{\bf M. Krishna, A. Mohari}}]\newline % \item{\bf Number Theory:} % Number theory is concerned mainly with the way prime numbers are distributed in the set of natural numbers. This area has rich interactions with many other branches of mathematics including algebra, complex analysis and geometry. There are also applications to cryptography.\newline % [{\small{\bf R. Balasubramanian, Kapil Paranjape, K. Srinivas, Anirban Mukhopadhyay, Sonali Gun}}]\newline \item{\bf Operator algebras:} This subject may loosely be described as the study of `infinite-dimensional matrices'. It was introduced by von Neumann in order to address some problems arising from quantum mechanics. Even today, it is intimately tied to various branches of physics as well as to other areas of pure mathematics, such as knot theory.\newline % [{\small{\bf Vijay Kodiyalam, V. S. Sunder, Partha Sarathi Chakraborty}}]\newline %\item{\bf Non-commutative Geometry:} % %This area is the study of geometry of space where points are taken to be %operators. %[{\small{\bf Partha Sarathi Chakraborty}}]\newline \item{\bf Partial Differential Equations:} Partial Differential equations (PDEs) arise when studying several problems in physics and engineering. The research done in this area includes the study of existence and multiplicity of solutions (of linear and nonlinear PDEs or systems of PDEs) and their qualitative properties such as their behaviour as various parameters tend to some limit, the estimation of their size in various norms and so on. The techniques used come from functional analysis and the calculus of variations (study of critical points of functionals defined on infinite dimensional spaces).\newline % [{\small{\bf S. Kesavan}}]\newline \item{\bf Representation theory:} % Groups are algebraic structures that arise as symmetries of physical or mathematical objects. Representation theory studies properties of abstract groups via their matrix representations. Representation theory enables many group-theoretic problems to be reduced to problems in matrix algebra, which is very well-understood. \newline % [{\small{\bf A. Prasad, K. N. Raghavan, P. Sankaran}}]\newline \item{\bf Topology:} % Topology may be described as geometry with or without a notion of distance. It aims to study properties of these objects, of which curves and surfaces are well-known examples, which are invariant under deformations. The subject has wide applications within mathematics as well as in physics.\newline % [{\small{\bf P. Sankaran}}]%\newline \end{itemize} \newpage \subsubsection{Theoretical Physics} \vspace{-1.0mm} The Theoretical Physics group subsumes a very broad spectrum of specializations. These are conveniently grouped under a smaller number of headings. A very brief description is provided followed by the names of faculty members currently working in these areas. \vspace{-2.0mm} In 2008-2009, a total of 71 articles were submitted/accepted for publication in journals and conference proceedings and a volume in Journal of Physics: conference Series, was edited. % 39?? % and 39?? were submitted/accepted for publication. \vspace{-2.0mm} \begin{itemize} \item {\bf Elementary Particle Physics:} The current status of our knowledge of the sub-nuclear constituents of nature and their properties is well summarized by the {\it Standard Model}. This model describes the strong and electro-weak interactions. The research involves both elaboration of the model as well as searching for clues to go beyond it. The following grouping refers to different aspects that are being pursued at IMSc. \newline \begin{itemize} \item{\bf Collider Physics:} The phenomenological aspects of physics at existing and future colliders are studied with a view to seek possible signals of New Physics (or Physics beyond the Standard Model). Globally the main focus is currently on the physics discovery potential of the upcoming Large Hadron Collider (LHC) at CERN in Geneva. India is an observer member at CERN, the European Organization for Nuclear Research. \newline [{\small {\bf Rahul Basu, Rahul Sinha}}]\newline \item {\bf Perturbative QCD:} This deals with the strong forces in the standard model particularly in the context of scattering processes.\newline [{\small {\bf Rahul Basu, D. Indumathi, M. V. N. Murthy}}] \newline \item {\bf Non-Perturbative QCD:} This deals with widely believed properties of strong forces such as ``color confinement'', ``color superconductivity'' and ``chiral symmetry breaking''. \newline [{\small {\bf Ramesh Anishetty, Sanatan Digal, Prashanth Jayakumar, H. S. Sharatchandra}}] \newline \item {\bf Neutrino Physics:} Neutrinos are very weakly interacting particles which have recently been found to be massive, going beyond the Standard Model. There is a national proposal to build a {\it Indian Neutrino Observatory} (INO).\newline [{\small {\bf D. Indumathi, M. V. N. Murthy, Nita Sinha}}] \newline \item {\bf CP-violation and B-Physics:} % Symmetries play a crucial role % in understanding the fundamental laws of nature. Several experiments worldwide are studying the physics of ``beauty mesons'' (B-physics) in order to explain the observed CP-violation (the dominance of matter over antimatter). Such studies are also important in the search for physics beyond the Standard Model. % % Symmetries play a crucial role % in building models. The combined invariance under charge conjugation and % parity is the CP symmetry. Its violation, which correlates with the % violation of `time reversal symmetry', is being investigated in both the % strong and the weak interactions. Physics involving the ``bottom % quark'' holds the promise of physics beyond the Standard Model. % \newline [{\small {\bf Nita Sinha, Rahul Sinha}}] \newline \item {\bf Gravitational Physics:} Einstein's theory of gravity has a bearing on the theory of our cosmos and also predicts exotic objects such as black holes. Its quantum version is being constructed in a variety of approaches such as string theory, loop quantum gravity, non-commutative geometry etc. Both classical and quantum aspects of gravity are being studied at IMSc. % \newline % [{\small {\bf Ghanashyam Date, T. R. Govindarajan, Romesh Kaul}}] % \newline \item {\bf Quantum Field Theory:} This provides a general theoretical framework for the quantum theory of fields. Apart from the perturbative analyses of quantum field theories used in the theory of scattering processes, their non-perturbative aspects are crucial for a more complete understanding. There are many different types of quantum field theories such as Conformal Field Theories, Topological Field Theories, Non-commutative Field Theories, Lattice Gauge Theories etc.\newline % [{\small {\bf Sanatan Digal, T. R. Govindarajan, Romesh Kaul, H. S. Sharatchandra}}] \newline \item {\bf String Theory:} In the quest for a unified framework to understand all interactions, string theory is the leading approach. At IMSc the focus has been on Calabi-Yau manifolds, loop variables approach, string dualities, brane physics including cosmology and black hole entropy. % \newline [{\small {\bf Sujay K. Ashok, T. Jayaraman, S. Kalyana Rama, Partha Mukhopadhyay, Balachandran Sathiapalan, Nemani V. Suryanarayana}}] % % \newline \end{itemize} \item {\bf Condensed Matter Physics:} The field of condensed matter physics deals with the understanding of the properties of materials. Materials display an amazingly diverse set of properties; for example, the resistivity of materials can vary over about 20 orders of magnitude depending on the material. Condensed matter physics attempts to understand the reasons behind such diversity of behaviour in terms of simpler models which can then be studied using a variety of theoretical and computational tools. \newline \begin{itemize} \item {\bf High Temperature Superconductivity:} At very low temperatures, several materials undergo a transition into a superconducting state, in which an electrical current flows without resistance. The properties of materials which superconduct at somewhat higher temperatures, the high-temperature superconductors, is one of the most active areas of research today, since it raises many theoretical questions of principle and has important implications for technology.\newline [{\small {\bf G. Baskaran, Gautam I. Menon}}] \newline \item {\bf Correlated Electronic Systems, Magnetism and the Quantum Hall Effect:} The interactions between electrons is responsible for magnetism. Such interactions are key to several unusual electronic states. Understanding this problem better would impact our understanding of a host of recently discovered materials with unusual properties. \newline [{\small {\bf G. Baskaran, Syed Raghib Hassan, A. K. Mishra, R. Shankar}}] \newline \item {\bf Electrochemistry, Chemisorption and Electron Transfer:} Electrochemistry is the science of the reactions that can take place at the interface of an electronic conductor (the electrode, which can be a metal or a semiconductor including graphite) and an ionic conductor (the electrolyte).\newline [{\small {\bf A. K. Mishra}}] \newline \item {\bf Soft Condensed Matter Physics:} Soft condensed matter refers to physical systems in which the energy scales required to create sizeable deformations are comparable to temperature. Thus, such systems can exhibit a remarkable variety of complex flow behaviour as well as equilibrium phases under relatively modest perturbations. \newline [{\small {\bf Ronojoy Adhikari, Gautam I. Menon}}] \newline \end{itemize} \vspace{-2.0mm} \item {\bf Statistical Mechanics:} The field of statistical mechanics provides a foundation for thinking about the collective behaviour of large numbers of interacting particles. The behaviour of systems out of thermal equilibrium is of particular interest, featuring such problems as fracture in disordered materials, hysteresis in magnets and surface growth. Given the generality of the approach of statistical mechanics, it finds application in a huge range of fields, including study of critical phenomena, statistical physics of surfaces and networks, granular system, statistical mechanics of materials, turbulence in liquids, the modeling of biological systems and even explaining socio-economic distributions such as that of income or stock price fluctuations. \newline [{\small {\bf Gautam I. Menon, M. V. N. Murthy, Purusattam Ray, R. Rajesh, Sitabhra Sinha}}] \newline \vspace{-2.0mm} \item {\bf Biological Physics and Computational Biology:} The field of the physics of biological systems is one of the most rapidly growing areas of physics today. Apart from more traditional sub-areas, this term is broadly defined to include fields such as computational biology, computational genomics and protein folding, where physicists have contributed and continue to contribute extensively.\newline [{\small {\bf Ramesh Anishetty, Gautam I. Menon, Rahul Siddharthan, Sitabhra Sinha, Satyavani Vemparala}}] \newline \vspace{-2.0mm} \item {\bf Non-linear Dynamics:} Nonlinear systems exhibit surprising and complex effects that would never be anticipated by a scientist trained only in linear techniques. Prominent examples of these include bifurcation, chaos, and solitons. Surprisingly, diverse non-linear dynamical systems exhibit remarkably similar, sometimes even universal behaviour. Nonlinear science has applications to a wide variety of fields, from mathematics, physics, biology, and chemistry, to engineering, economics, and medicine.\newline [{\small {\bf Radha Balakrishnan, R. Jagannathan, Sitabhra Sinha, Sudeshna Sinha}}] \newline \vspace{-2.0mm} \item {\bf Quantum Physics:} This is a grouping of areas not subsumed under the above headings and contains the following specializations. \newline \vspace{-2.0mm} \begin{itemize} \item {\bf Particle Beam Optics:} Many physics experiments, notably accelerator experiments, involve particle beams. Their quantum mechanical transport properties are being studied.\newline [{\small {\bf R. Jagannathan}}] \newline % \item {\bf Quantum Optics:} Broadly, this area refers to the study of quantum states of light. At IMSc, the focus in this area has been on specifically non-classical (quantum) aspects of radiation. Other related interests %have been and are geometric phases, Wigner distribution functions for finite dimensional Hilbert spaces etc.\newline [{\small {\bf R. Simon, Sibasish Ghosh}}] \newline \vspace{-2.0mm} \item {\bf Quantum Entanglement, Quantum Information Theory:} Classical states have definite attributes while quantum states can exist as ``superpositions'' and have non-classical (probabilistic) attributes. This feature affects aspects of information science such as coding/decoding, transmission, computing etc. Aspects of quantum information theory in the context of finite dimensional as well as infinite dimensional quantum state spaces are being studied.\newline [{\small {\bf R. Simon, V. Arvind, Sibasish Ghosh}}] %\newline \end{itemize} \end{itemize} \subsubsection{Theoretical Computer Science} \vfill Theoretical computer science is mainly concerned with the mathematical structure of computations (as distinct from software development). There are various aspects of the field that are of interest to the group at IMSc. A very brief description of these specializations is provided followed by the names of faculty members currently working in these areas. \vfill In 2008-2009, a total of 34 articles were submitted/accepted/published in journals and conference proceedings and 2 books were edited. \vfill \begin{itemize} % \item {\bf Algorithms and Data Structures:} % % The main goal of this area is the design of efficient methods for solving various computational problems and developing methods for analyzing their performance in terms of the resources used (eg. time, space) and the quality of the solution. It also involves developing means of storing information, with small space requirements, and supporting efficient access and update operations. \newline % [{\small{\bf V. Arvind, Meena B. Mahajan, Venkatesh Raman, C. R. Subramanian}}] \newline \vfill \item {\bf Computational Complexity:} % Broadly speaking, computational complexity theory is the study of bounds on resources such as time and space required for solving computational problems. The theory aims at a classification of problems into various complexity classes defined by resource bounds and seeks to separate them by proving lower bounds and upper bounds on resources required by the problems. \newline % [{\small{\bf V. Arvind, Meena B. Mahajan}}] \newline \vfill \item {\bf Graph theory and Combinatorics:} % This area is the mathematical study of discrete objects with applications to various branches of Computer Science. It uses tools from various branches of mathematics such as probability theory, algebra, etc.\newline % [{\small{\bf Venkatesh Raman, C. R. Subramanian}}]\newline \item {\bf Formal models:} % This area is concerned with three main aspects: developing and comparing different mathematical models of computation, developing and analyzing different tools for logical reasoning as well as applying them to computational processes and the connection between automata, logic and algebra. \newline % [{\small{\bf Kamal Lodaya, R. Ramanujam}}] %\newline \vfill \end{itemize} \newpage \subsection{Teaching Programmes} An integral part of sustained research activity is training future generations of scientists and mathematicians. At IMSc this is done by supervising postgraduate and doctoral level thesis work. Motivated and bright students at the graduate and post-graduate level are selected every year through a national level Joint Entrance Screening Test followed by an interview. The selected students receive a fellowship throughout their tenure. They undergo one or two years of course-work, followed by doctoral thesis work under the guidance of a faculty member. During 2008-2009, the student strength is 84 with 23 in Mathematics, 36 in Physics and 25 in Theoretical Computer Science. {\it Six} students have submitted their doctoral theses. A total of 50 courses, in all three disciplines and some for the undergraduate programme of CMI, were taught at IMSc during 2008-2009. Apart from this main training activity, IMSc also offers the opportunity of learning for a few students during the summer vacation period. These students spend up to 6 weeks doing projects with faculty members. The faculty also supervises short-term projects during other periods. A total of 30 students availed these opportunities during 2008-2009. \subsection{Scientific Meetings and Visitor Program} The academic members of the Institute typically participate extensively in a large number of national and international scientific meetings.

During 2008-2009 around 124 scientists visited the Institute. \newpage \subsection{Collaborative Projects} Institute members are also involved in joint projects with colleagues from other national and international institutes. The following projects are ongoing: \begin{itemize} \vspace{-1.0mm} \item {\bf India-based Neutrino Observatory:} The INO proposal is currently with the Government of India and included in the Mega Science Project proposals. The project is awaiting approval. INO group at IMSc is an active participant in the collaboration. The INO group at IMSc consists of D. Indumathi, H.S. Mani, M.V.N. Murthy, G. Rajasekaran and Nita Sinha. In addition, two full time project members N.S. Srinivasan and D.V. Ramakrishna are involved in the INO group activities at IMSc. The IMSc group is also involved in analysing the Physics and Simulation issues relevant to the Magnetised Iron Calorimeter (ICAL) detector at INO. Apart from the physics results that can be studied with atmospheric neutrinos and neutrinos from long base-line neutrino beams, the group is also engaged in studies such as track recognition and reconstruction using ICAL detector. The members of the group are taking active part in outreach activities, by giving popular lectures at various universities and other such institutions with the long term goal of creating awareness and interest in INO as well as generate human resources necessary for such a large project at a future time. \item{\bf Physical Properties Relevant to Nanoscale Devices and Biological Motors in the Brownian Regime :} This is a joint project of Gautam I. Menon of IMSc with A.M. Jayannavar (IOP, Bhubaneswar) and Surajit Sengupta (SNBNCBS, Kolkata), funded by the Nanoscience and Nanotechnology Initiative of the DST, India. Our general goal in this project is posed in terms of the following questions which we will attempt to address: What are the generic ingredients of models for machines which can do work in a thermal (Brownian) environment? How do physics requirements constrain the design, performance and efficiency of nanoscale machines? Are there general principles governing how biological systems perform work at the nano-scale? Can we use models devised for understanding the functioning of nano-scale biological motors for insights into guiding principles for the construction of man-made devices at that scale? Finally, what materials properties of nano-scale devices might be optimally selected if they are to be used as machine components? \item{\bf Provably Efficient Exact Algorithms for NP-hard problems :} This is a DST-DAAD joint project with Venkatesh Raman, Somnath Sikdar and Saket Saurabh of theoretical computer science and the research group of Prof. Rolf Niedermier of University of Jena, Germany and two of his students. The aim of the project is to address problems in exact and parameterized computations utilizing the common interests and complementary skill set of the two groups. The project supports a fixed number of mutual visits of the scientists in the project. Under this project, Somnath Sikdar visited Jena University and Hannes Moser visited IMSc during this year. % %\\ \vfill \item{\bf The Debian Project} The Debian project was established in 1993 to provide an operating system that is composed of entirely free software. The IMSc is one of the few academic institutions in India that runs all its services on free software; indeed it has been a pioneer in this area. In earlier years our contribution has been restricted to reporting bugs and patches for those bugs. Since November 2004 we have been maintaining some packages that are used by the wide community of Debian users. This project is carried out by Kapil H. Paranjape. \item{\bf The Mechanics of Living Matter :} This is a joint project of Gautam I. Menon of IMSc and Sriram Ramaswamy (IISc, Bangalore), Jacques Prost (ESPCI, Paris), J.-F Joanny (Institut Curie, Paris), Madan Rao (RRI and NCBS, Bangalore), Yashodhan Hatwalne (RRI, Bangalore) and David Lacoste (ESPCI, Paris) and funded by the Indo-French Centre for the Promotion of Advanced Research (CEFIPRA). The project will focuss on active systems, i.e. systems which contain components which are capable of taking up energy from their surroundings and turning it into motion via an irreversible chemical reaction. They arise primarily in biology, but soft-matter and nonequilibrium statistical physics are essential to understanding them. \item {\bf Electron Transport along Monoatomic Electrochemical Wire and chains:} A DST-DAAD project on Electron Transport along Monoatomic Electrochemical Wire and chains, involving IMSc and University of Ulm, Germany. A.K. Mishra and Vallan Bruno Cruz are the project members from Indian side and Prof. W. Schmickler and Ms. Sonja Bartenschlager are German participants. \item {\bf Belle Colaboration:} BELLE is an international collaboration of 371 physicists from 14 countries (Australia, Austria, China, Germany, India, Italy, Japan, Korea, Poland, Russia, Slovenia, Switzerland, Taiwan, and USA ) and 60 institutions that are invovled in research pertaining to matter-antimatter differences and the study of other phenomenon accessible at the KEK-B collider operated by High Energy Accelerator Research Organization in Tsukuba, Japan. Rahul Sinha of IMSc was invited to join the Belle collaboration and is a member of Belle since July 2008. %%\item{\bf The Mechanics of Living Matter :} This is a joint project of %% Gautam I.

Research output is disseminated primarily as refereed journal articles as well as articles in conference proceedings. The expertise available at the institute is organized below according to the areas of specialization. % \vspace{-5.0mm} \subsubsection{Mathematics} \vspace{-4.0mm} % The Mathematics group has wide ranging interests. These specializations are conveniently grouped together under broad headings. A very brief description is provided followed by the names of faculty members currently working in these areas. In 2008-2009, a total of 59 articles were submitted/accepted/published in journals and conference proceedings. \vspace{-2.0mm} \begin{itemize} \item{\bf Algebra:} % Algebra is the study of the properties of mathematical structures involving ``algebraic'' operations such as addition and multiplication. One of the main motivations to study algebraic structures is to analyze geometric objects such as curves and surfaces via the algebra of functions defined on them. Aspects of algebra being studied at IMSc involve algebraic geometry (study of loci of solutions of polynomial equations), algebraic groups (groups of matrices), and the theory of knots. \newline % [{\small{\bf Vijay Kodiyalam, D. S. Nagaraj, K. N. Raghavan.}}]\newline \item{\bf Algebraic Geometry:} % This branch of mathematics is a study of the solution set of a finite set of polynomials in several variables. The total degrees of the polynomials and the number of polynomials play an important role in determining the geometry of the solution set. This subject has rich interactions with mathematical physics and other areas.\newline % [{\small{\bf Jaya Iyer, Kapil Paranjape, D. S. Nagaraj}}]\newline % \item{\bf Mathematical physics:} % An important area of mathematical physics is the spectral theory of Schr\"odinger operators. Such operators arise in describing the quantum mechanics of particles. The spectrum of such an operator gives the possible energies of the quantum system. The operators are considered both for deterministic as well as random potentials and the focus is on obtaining the spectrum rigorously. \newline Another area of study is the quantum spin chains, where the ground state of various models is studied for its uniqueness. Another major question in the area is the existence of a mass gap. In addition to these entropy of quantum dynamical systems is studied. % [{\small{\bf M. Krishna, A. Mohari}}]\newline \item{\bf Number Theory:} % Number theory is concerned mainly with the way prime numbers are distributed in the set of natural numbers. This area has rich interactions with many other branches of mathematics including algebra, complex analysis and geometry. There are also applications to cryptography.\newline % [{\small{\bf R. Balasubramanian, Kapil Paranjape, K. Srinivas, Anirban Mukhopadhyay, Sonali Gun}}]\newline \item{\bf Operator algebras:} This subject may loosely be described as the study of `infinite-dimensional matrices'. It was introduced by von Neumann in order to address some problems arising from quantum mechanics. Even today, it is intimately tied to various branches of physics as well as to other areas of pure mathematics, such as knot theory.\newline % [{\small{\bf Vijay Kodiyalam, V. S. Sunder, Partha Sarathi Chakraborty}}]\newline %\item{\bf Non-commutative Geometry:} % %This area is the study of geometry of space where points are taken to be %operators. %[{\small{\bf Partha Sarathi Chakraborty}}]\newline \item{\bf Partial Differential Equations:} Partial Differential equations (PDEs) arise when studying several problems in physics and engineering. The research done in this area includes the study of existence and multiplicity of solutions (of linear and nonlinear PDEs or systems of PDEs) and their qualitative properties such as their behaviour as various parameters tend to some limit, the estimation of their size in various norms and so on. The techniques used come from functional analysis and the calculus of variations (study of critical points of functionals defined on infinite dimensional spaces).\newline % [{\small{\bf S. Kesavan}}]\newline \item{\bf Representation theory:} % Groups are algebraic structures that arise as symmetries of physical or mathematical objects. Representation theory studies properties of abstract groups via their matrix representations. Representation theory enables many group-theoretic problems to be reduced to problems in matrix algebra, which is very well-understood. \newline % [{\small{\bf A. Prasad, K. N. Raghavan, P. Sankaran}}]\newline \item{\bf Topology:} % Topology may be described as geometry with or without a notion of distance. It aims to study properties of these objects, of which curves and surfaces are well-known examples, which are invariant under deformations. The subject has wide applications within mathematics as well as in physics.\newline % [{\small{\bf P. Sankaran}}]%\newline \end{itemize} \newpage \subsubsection{Theoretical Physics} \vspace{-1.0mm} The Theoretical Physics group subsumes a very broad spectrum of specializations. These are conveniently grouped under a smaller number of headings. A very brief description is provided followed by the names of faculty members currently working in these areas. \vspace{-2.0mm} In 2008-2009, a total of 73 articles were submitted/accepted for publication in journals and conference proceedings and a volume in Journal of Physics: conference Series, was edited. % 39?? % and 39?? were submitted/accepted for publication. \vspace{-2.0mm} \begin{itemize} \item {\bf Elementary Particle Physics:} The current status of our knowledge of the sub-nuclear constituents of nature and their properties is well summarized by the {\it Standard Model}. This model describes the strong and electro-weak interactions. The research involves both elaboration of the model as well as searching for clues to go beyond it. The following grouping refers to different aspects that are being pursued at IMSc. \newline \begin{itemize} \item{\bf Collider Physics:} The phenomenological aspects of physics at existing and future colliders are studied with a view to seek possible signals of New Physics (or Physics beyond the Standard Model). Globally the main focus is currently on the physics discovery potential of the upcoming Large Hadron Collider (LHC) at CERN in Geneva. India is an observer member at CERN, the European Organization for Nuclear Research. \newline [{\small {\bf Rahul Basu, Rahul Sinha}}]\newline \item {\bf Perturbative QCD:} This deals with the strong forces in the standard model particularly in the context of scattering processes.\newline [{\small {\bf Rahul Basu, D. Indumathi, M. V. N. Murthy}}] \newline \item {\bf Non-Perturbative QCD:} This deals with widely believed properties of strong forces such as ``color confinement'', ``color superconductivity'' and ``chiral symmetry breaking''. \newline [{\small {\bf Ramesh Anishetty, Sanatan Digal, Prashanth Jayakumar, H. S. Sharatchandra}}] \newline \item {\bf Neutrino Physics:} Neutrinos are very weakly interacting particles which have recently been found to be massive, going beyond the Standard Model. There is a national proposal to build a {\it Indian Neutrino Observatory} (INO).\newline [{\small {\bf D. Indumathi, M. V. N. Murthy, Nita Sinha}}] \newline \item {\bf CP-violation and B-Physics:} % Symmetries play a crucial role % in understanding the fundamental laws of nature. Several experiments worldwide are studying the physics of ``beauty mesons'' (B-physics) in order to explain the observed CP-violation (the dominance of matter over antimatter). Such studies are also important in the search for physics beyond the Standard Model. % % Symmetries play a crucial role % in building models. The combined invariance under charge conjugation and % parity is the CP symmetry. Its violation, which correlates with the % violation of `time reversal symmetry', is being investigated in both the % strong and the weak interactions. Physics involving the ``bottom % quark'' holds the promise of physics beyond the Standard Model. % \newline [{\small {\bf Nita Sinha, Rahul Sinha}}] \newline \item {\bf Gravitational Physics:} Einstein's theory of gravity has a bearing on the theory of our cosmos and also predicts exotic objects such as black holes. Its quantum version is being constructed in a variety of approaches such as string theory, loop quantum gravity, non-commutative geometry etc. Both classical and quantum aspects of gravity are being studied at IMSc. % \newline % [{\small {\bf Ghanashyam Date, T. R. Govindarajan, Romesh Kaul}}] % \newline \item {\bf Quantum Field Theory:} This provides a general theoretical framework for the quantum theory of fields. Apart from the perturbative analyses of quantum field theories used in the theory of scattering processes, their non-perturbative aspects are crucial for a more complete understanding. There are many different types of quantum field theories such as Conformal Field Theories, Topological Field Theories, Non-commutative Field Theories, Lattice Gauge Theories etc.\newline % [{\small {\bf Sanatan Digal, T. R. Govindarajan, Romesh Kaul, H. S. Sharatchandra}}] \newline \item {\bf String Theory:} In the quest for a unified framework to understand all interactions, string theory is the leading approach. At IMSc the focus has been on Calabi-Yau manifolds, loop variables approach, string dualities, brane physics including cosmology and black hole entropy. % \newline [{\small {\bf Sujay K. Ashok, T. Jayaraman, S. Kalyana Rama, Partha Mukhopadhyay, Balachandran Sathiapalan, Nemani V. Suryanarayana}}] % % \newline \end{itemize} \item {\bf Condensed Matter Physics:} The field of condensed matter physics deals with the understanding of the properties of materials. Materials display an amazingly diverse set of properties; for example, the resistivity of materials can vary over about 20 orders of magnitude depending on the material. Condensed matter physics attempts to understand the reasons behind such diversity of behaviour in terms of simpler models which can then be studied using a variety of theoretical and computational tools. \newline \begin{itemize} \item {\bf High Temperature Superconductivity:} At very low temperatures, several materials undergo a transition into a superconducting state, in which an electrical current flows without resistance. The properties of materials which superconduct at somewhat higher temperatures, the high-temperature superconductors, is one of the most active areas of research today, since it raises many theoretical questions of principle and has important implications for technology.\newline [{\small {\bf G. Baskaran, Gautam I. Menon}}] \newline \item {\bf Correlated Electronic Systems, Magnetism and the Quantum Hall Effect:} The interactions between electrons is responsible for magnetism. Such interactions are key to several unusual electronic states. Understanding this problem better would impact our understanding of a host of recently discovered materials with unusual properties. \newline [{\small {\bf G. Baskaran, Syed Raghib Hassan, A. K. Mishra, R. Shankar}}] \newline \item {\bf Electrochemistry, Chemisorption and Electron Transfer:} Electrochemistry is the science of the reactions that can take place at the interface of an electronic conductor (the electrode, which can be a metal or a semiconductor including graphite) and an ionic conductor (the electrolyte).\newline [{\small {\bf A. K. Mishra}}] \newline \item {\bf Soft Condensed Matter Physics:} Soft condensed matter refers to physical systems in which the energy scales required to create sizeable deformations are comparable to temperature. Thus, such systems can exhibit a remarkable variety of complex flow behaviour as well as equilibrium phases under relatively modest perturbations. \newline [{\small {\bf Ronojoy Adhikari, Gautam I. Menon}}] \newline \end{itemize} \vspace{-2.0mm} \item {\bf Statistical Mechanics:} The field of statistical mechanics provides a foundation for thinking about the collective behaviour of large numbers of interacting particles. The behaviour of systems out of thermal equilibrium is of particular interest, featuring such problems as fracture in disordered materials, hysteresis in magnets and surface growth. Given the generality of the approach of statistical mechanics, it finds application in a huge range of fields, including study of critical phenomena, statistical physics of surfaces and networks, granular system, statistical mechanics of materials, turbulence in liquids, the modeling of biological systems and even explaining socio-economic distributions such as that of income or stock price fluctuations. \newline [{\small {\bf Gautam I. Menon, M. V. N. Murthy, Purusattam Ray, R. Rajesh, Sitabhra Sinha}}] \newline \vspace{-2.0mm} \item {\bf Biological Physics and Computational Biology:} The field of the physics of biological systems is one of the most rapidly growing areas of physics today. Apart from more traditional sub-areas, this term is broadly defined to include fields such as computational biology, computational genomics and protein folding, where physicists have contributed and continue to contribute extensively.\newline [{\small {\bf Ramesh Anishetty, Gautam I. Menon, Rahul Siddharthan, Sitabhra Sinha, Satyavani Vemparala}}] \newline \vspace{-2.0mm} \item {\bf Non-linear Dynamics:} Nonlinear systems exhibit surprising and complex effects that would never be anticipated by a scientist trained only in linear techniques. Prominent examples of these include bifurcation, chaos, and solitons. Surprisingly, diverse non-linear dynamical systems exhibit remarkably similar, sometimes even universal behaviour. Nonlinear science has applications to a wide variety of fields, from mathematics, physics, biology, and chemistry, to engineering, economics, and medicine.\newline [{\small {\bf Radha Balakrishnan, R. Jagannathan, Sitabhra Sinha, Sudeshna Sinha}}] \newline \vspace{-2.0mm} \item {\bf Quantum Physics:} This is a grouping of areas not subsumed under the above headings and contains the following specializations. \newline \vspace{-2.0mm} \begin{itemize} \item {\bf Particle Beam Optics:} Many physics experiments, notably accelerator experiments, involve particle beams. Their quantum mechanical transport properties are being studied.\newline [{\small {\bf R. Jagannathan}}] \newline % \item {\bf Quantum Optics:} Broadly, this area refers to the study of quantum states of light. At IMSc, the focus in this area has been on specifically non-classical (quantum) aspects of radiation. Other related interests %have been and are geometric phases, Wigner distribution functions for finite dimensional Hilbert spaces etc.\newline [{\small {\bf R. Simon, Sibasish Ghosh}}] \newline \vspace{-2.0mm} \item {\bf Quantum Entanglement, Quantum Information Theory:} Classical states have definite attributes while quantum states can exist as ``superpositions'' and have non-classical (probabilistic) attributes. This feature affects aspects of information science such as coding/decoding, transmission, computing etc. Aspects of quantum information theory in the context of finite dimensional as well as infinite dimensional quantum state spaces are being studied.\newline [{\small {\bf R. Simon, V. Arvind, Sibasish Ghosh}}] %\newline \end{itemize} \end{itemize} \subsubsection{Theoretical Computer Science} \vfill Theoretical computer science is mainly concerned with the mathematical structure of computations (as distinct from software development). There are various aspects of the field that are of interest to the group at IMSc. A very brief description of these specializations is provided followed by the names of faculty members currently working in these areas. \vfill In 2008-2009, a total of 45 articles were submitted/accepted/published in journals and conference proceedings and 2 books were edited. \vfill \begin{itemize} % \item {\bf Algorithms and Data Structures:} % % The main goal of this area is the design of efficient methods for solving various computational problems and developing methods for analyzing their performance in terms of the resources used (eg. time, space) and the quality of the solution.

Mahajan, Venkatesh Raman, C. R. Subramanian}}] \newline \vfill \item {\bf Computational Complexity:} % Broadly speaking, computational complexity theory is the study of bounds on resources such as time and space required for solving computational problems. The theory aims at a classification of problems into various complexity classes defined by resource bounds and seeks to separate them by proving lower bounds and upper bounds on resources required by the problems. \newline % [{\small{\bf V. Arvind, Meena B. Mahajan}}] \newline \vfill \item {\bf Graph theory and Combinatorics:} % This area is the mathematical study of discrete objects with applications to various branches of Computer Science.

At IMSc this is done by supervising postgraduate and doctoral level thesis work. Motivated and bright students at the graduate and post-graduate level are selected every year through a national level Joint Entrance Screening Test followed by an interview. The selected students receive a fellowship throughout their tenure. They undergo one or two years of course-work, followed by doctoral thesis work under the guidance of a faculty member. During 2008-2009, the student strength is 82 with 23 in Mathematics, 36 in Physics and 23 in Theoretical Computer Science. {\it Four} students have submitted their doctoral theses. A total of 44 courses, in all three disciplines and some for the undergraduate programme of CMI, were taught at IMSc during 2008-2009. Apart from this main training activity, IMSc also offers the opportunity of learning for a few students during the summer vacation period. These students spend up to 6 weeks doing projects with faculty members. The faculty also supervises short-term projects during other periods. A total of 13 students availed these opportunities during 2008-2009. \subsection{Scientific Meetings and Visitor Program} The academic members of the Institute typically participate extensively in a large number of national and international scientific meetings. An important component of research is the organization of national and international scientific meetings.

During 2008-2009 around 124 scientists visited the Institute. \newpage \subsection{Collaborative Projects} Institute members are also involved in joint projects with colleagues from other national and international institutes. The following projects are ongoing: \begin{itemize} \vspace{-1.0mm} \item {\bf India-based Neutrino Observatory:} The INO proposal is currently with the Government of India and included in the Mega Science Project proposals. The project is awaiting approval. INO group at IMSc is an active participant in the collaboration. The INO group at IMSc consists of D. Indumathi, H.S. Mani, M.V.N. Murthy, G. Rajasekaran and Nita Sinha. In addition, two full time project members N.S. Srinivasan and D.V. Ramakrishna are involved in the INO group activities at IMSc. The IMSc group is also involved in analysing the Physics and Simulation issues relevant to the Magnetised Iron Calorimeter (ICAL) detector at INO. Apart from the physics results that can be studied with atmospheric neutrinos and neutrinos from long base-line neutrino beams, the group is also engaged in studies such as track recognition and reconstruction using ICAL detector. The members of the group are taking active part in outreach activities, by giving popular lectures at various universities and other such institutions with the long term goal of creating awareness and interest in INO as well as generate human resources necessary for such a large project at a future time. \item{\bf Physical Properties Relevant to Nanoscale Devices and Biological Motors in the Brownian Regime :} This is a joint project of Gautam I. Menon of IMSc with A.M. Jayannavar (IOP, Bhubaneswar) and Surajit Sengupta (SNBNCBS, Kolkata), funded by the Nanoscience and Nanotechnology Initiative of the DST, India. Our general goal in this project is posed in terms of the following questions which we will attempt to address: What are the generic ingredients of models for machines which can do work in a thermal (Brownian) environment? How do physics requirements constrain the design, performance and efficiency of nanoscale machines? Are there general principles governing how biological systems perform work at the nano-scale? Can we use models devised for understanding the functioning of nano-scale biological motors for insights into guiding principles for the construction of man-made devices at that scale? Finally, what materials properties of nano-scale devices might be optimally selected if they are to be used as machine components? \item{\bf Provably Efficient Exact Algorithms for NP-hard problems :} This is a DST-DAAD joint project with Venkatesh Raman, Somnath Sikdar and Saket Saurabh of theoretical computer science and the research group of Prof. Rolf Niedermier of University of Jena, Germany and two of his students. The aim of the project is to address problems in exact and parameterized computations utilizing the common interests and complementary skill set of the two groups. The project supports a fixed number of mutual visits of the scientists in the project. Under this project, Somnath Sikdar visited Jena University and Hannes Moser visited IMSc during this year. % %\\ \vfill \item{\bf The Debian Project} The Debian project was established in 1993 to provide an operating system that is composed of entirely free software. The IMSc is one of the few academic institutions in India that runs all its services on free software; indeed it has been a pioneer in this area. In earlier years our contribution has been restricted to reporting bugs and patches for those bugs. Since November 2004 we have been maintaining some packages that are used by the wide community of Debian users. This project is carried out by Kapil H. Paranjape. \item{\bf The Mechanics of Living Matter :} This is a joint project of Gautam I.
