Research

Dhar works on the theory and applications of statistical physics to study non-equilibrium problems. His research areas include anomalous heat transport in low dimensional systems and

open quantum system In physics, an open quantum system is a quantum-mechanical system that interacts with an external quantum system, which is known as the ''environment'' or a ''bath''. In general, these interactions significantly change the dynamics of the system a ...

s where he made significant contributions in developing an approach using quantum Langevin equations. Dhar also studies large deviations and fluctuation theorems in transport, foundational aspects of statistical mechanics, the measurement problem in quantum mechanics and models of

active matter Active matter is matter composed of large numbers of active "agents", each of which consumes energy in order to move or to exert mechanical forces. Such systems are intrinsically out of thermal equilibrium. Unlike thermal systems relaxing toward ...
