Theoretical Condensed Matter Physics. In particular,
(i) Strange metallicity and breakdown of perturbation theory near orbital/momentum selective Mott criticality, and its instabilities to novel order.
(ii) LDA+DMFT for d- and f-band correlated systems: half-metallicity, CDW in di- and trichalcogenides, superconductivity in Fe-arsenides, Dirac and Weyl semimetals.
(iii) Spin and Orbital liquids in lower dimensions D=1,2. Novel ground states, and anomaous One- and two-particle dynamical responses. Applcations to Josephson arrays and cavity-QED with an eye on physical realizations of qubit arrays for quantum computation.
(iv) Development of many-body tools for advanced electronic structure that incorporate short-range order in calculations of disordered alloys. Interest in exploring Electrochemistry with modern many body techniques.
(v) Exact results: Use of rigoorous inequalities. Bethe anastz in novel settings in D=1.
(i) B.Sc (Bombay Univ.), 1986.
(ii) M.Sc (IIT, Bombay), 1988.
(iii) Ph.D (IIT, Bombay), 1995, in THeoretical Condensed Matter Physics.
(i) Humboldt fellow at the MPIPKS, Dresden, Germany, from 1996-1998.
(ii) Postdoctoral Fellow at Universitaet zu Koeln, Germany, from 1998-2003.
(iii) EPSRC Fellow at Loughbrough University, UK from 2004-2006
(iv) Visiting Scientist at MPIPKS, Dresden, Germany, from 2006-2009.
(v) Universitaets-Docent at Aachen University, Germany, from 2010-2011.
(vi) Visiting Scientist, Instt Laue Langevin, Grenoble, France, from 2012-2013.
Presently, I am an Associate Professor at IMSc, India
I have taught Basic and Advanced Condensed Matter Physics and Mathematical Physics to students at IMSc during the last 4 years.
