Research in this group is in the theory and applications of nonequilibrium statistical mechanics to a variety of systems. Some of the areas of interest are:
- Transport: Anomalous heat transport refers to the observation, based on extensive simulations and some analytic results, that in low dimensional macroscopic systems Fourier’s law of heat conduction is not valid. In our group, efforts are focused on establishing this and in finding the correct hydrodynamic description of such systems. There is also interest in studying heat and electron transport across small quantum systems - here one would like to see the effects of nonequilibrium driving in small interacting quantum systems.
- Nonequilibrium fluctuation theorems: There have been recent attempts to extend the results of linear response theory to systems far from equilibrium. The full implications and generality of these results is not yet known and some aspects of these are being studied here.
- Turbulence: One of the last great unsolved problem of classical physics, this is not a single problem but a collection of many important problems. In our group, some of the problems that we look at, include a) statistical studies of fluid, magnetohydrodynamic, passive-scalar, and Burgers turbulence; b) Inertial (finite-size) particles in turbulent flows; c) Truncated systems and thermalization; and d) Singularities in the equations of hydrodynamics. Our research involves application of ideas in statistical physics, state-of-the-art simulations as well as obtaining various mathematical results in this field. Furthermore, our group is strongly coupled with various experimental groups working in this field.
- Some other areas of study include driven granular gases and tagged particle diffusion.
