Current Research
Our current research is mainly focused on addressing some of the fundamental challenges associated with nanoscience. Specifically, we try to answer some of the open questions pertaining to the electron (both charge and spin) transfer process involving nanoscale junction in a non equilibrium condition using quantum many body theory.
