Areas of Research/Interest: Strongly correlated systems, quantum phase transitions, nanoscale physics, dissipative and nonequilibrium phenomena.

My main research interest is the theoretical study of a variety of quantum many-particle systems that have been driven far out of equilibrium. Some examples are:

a). Nonequilibrium quantum impurity models which capture various nanoscale phenomena such as the effect of current induced decoherence on a localized spin.

b). Current driven phase transitions and instabilities in magnetic and superconducting systems.

c). Nonequilibrium dynamics of quantum many-particle systems arising due to the application of sudden time-dependent perturbations.
