Research Interests

My field of research is Statistical Physics and Nonlinear Dynamics. A system of a large number of interacting particles often displays a variety of emergent phenomena that are qualitatively different from the behavior of a single or a few particles. Prominent examples are magnetism, spontaneous synchronization (think of the pacemaker cells of the heart all spontaneously sending out synchronized electrical signals to contract the heart), etc. In such systems, the behavior often changes suddenly and dramatically as external tuning parameters like temperature, magnetic field, etc. are varied. Statistical mechanics provides the right (and the only) framework to understand and predict the static and dynamic properties of these systems.

Over the years, I have worked on a wide spectrum of topics in statistical physics and nonlinear dynamics: stochastic processes, fluctuation theorems, quantum dynamics, synchronization phenomena, and long-range interacting systems on which I have worked extensively. Applications of my work have been to areas such as astrophysical, condensed matter and biological systems. An underlying theme of my work is characterization of statics and dynamics of complex systems and study of how long-range interactions and/or correlations lead to emergent behaviors in such systems.
