  • Proton Decay in higher dimensions 
    Turbasu Biswas (2009-10-27)
    Proton decay is used as a guiding principle for the search of a Grand unified theory. As a starting point minimal nonsupersymmetric SU(5) model is taken as it is the simplest possible grand unified model. Then modifications ...

    Alok Kumar (, 2009-10-23)
    The non-perturbative aspects of QCD, the gauge theory of strong interactions are studied. The phenomenon of confinement of quarks and the dynamical chiral symmetry breaking are examined. The phenomenological linear ...
  • A Microscopic model for Microtubules 
    Mithun Kumar Mitra (2009-10-19)
    The controlled polymerization and depolymerization of biological macromolecules, such as Microtubules plays an important role in the process of force generating mechanisms in living cells. There has been much activity in ...
  • A Comparative study of string theory and loop quantum gravity in cosmological context 
    Kinjal Banerjee (, 2009-10-07)
    As per this study a possible comparison between String Theory and Loop Quantum Gravity is conceivable only at perturbative level in the large volume(in Planck units) limit. The simplest context of homogeneous isotropic ...

    Arjun Bagchi (, 2009-10-05)
    The general theory of Relativity and the scalar-Tensor theory are studied in general D dimensions stressing on Cosmology and the static spherically Schwarzchild solution. General Relativity is dealt with in Brief. Different ...
  • On Polynomial Identity Testing and Related Problems[HBNI Th12] 
    Partha Mukhopadhyay (The Institute of Mathematical Sciences, 2009)
    The polynomial identity Testing problem and its connection to several other important complexity theoretic problems are studied in this thesis. Polynomial identity testing problem is considered over commutative and non ...
  • Parameterized field theories and Loop Quantization[HBNI Th10] 
    Alok Laddha (The Institute of Mathematical Sciences, 2009)
    This thesis shows how two dimensional parametrized field theories constitute perfect toy models for Loop Quantum Gravity. Two dimensional massless scalar field theories on a Minkowskian plane and show how various aspects ...
  • Modelling Biological clocks: a study of the Repressilator 
    Somdeb Ghosh (The Institute of Mathematical Sciences, 2009-09-29)
    Biological clocks are found everywhere in the natural world. From circadian rhythms to pacemakers of the heart, biological clocks are an essential part of the smooth functioning of living organisms. They are composed of ...
  • Geometry of Quantum States 
    Sandeep, K. Goyal (, 2009-09-25)
    Understanding the geometry of state space is of fundamental interest in the field of quantum information, in particular to study entanglement. The states of a d-dimensional system form a convex set in the d^2 - 1 dimensional ...
  • Brusselator as a Reaction-Diffusion system 
    Rajeev Singh (, 2009-09-24)
