Research is aimed both at clarification of the microscopic origin of black hole entropy and interplay of mathematics and black hole physics. On the other hand, we study applications of black hole physics to study the characteristics of boundary plasma (QCD, Superfluids etc:) in the context of the AdS/CFT conjecture. We are also interested in studying properties of non-relativistic fluids, using higher dimensional black hole solutions via holography. Another area of our research interests is understanding the importance of symmetry to the dynamics of a theory. In particular, we study the implications of asymptotic symmetries of spacetimes to Quantum Field Theories on asymptotically flat and Anti de-Sitter spaces.
The main interest of our group lies in understanding the fundamental components of nature and the fundamental forces acting on them. The current Standard Model of Particle Physics provides a good understanding of these but still leaves many questions unanswered. Chief among them are the questions regarding neutrino and dark matter physics. They are widely expected to be the gateway to the hitherto unknown new physics beyond the Standard Model. Our group works on various theoretical as well as phenomenological aspects of the new physics beyond Standard Model.
