Statistical Physics
One of the grand challenge of statistical physics in the twenty-first century is to describe non-equilibrium systems. Modern non-equilibrium statistical mechanics requires generalizations of many traditional thermodynamic concepts, most of which are currently poorly understood. Our group has been working on many novel problems in the area of non-equilibrium physics, such as collective behavior, phase transitions, Langevin dynamics, Smoluchowski equation, dynamically driven renormalization group, discrete-time quantum walk, Crooks fluctuation theorem, noise-induced shape transitions, complex networks, etc. Some noteworthy past projects are listed below:
