Title: Asymmetric Exclusion process: a paradigm to study nonequilibrium dynamics.
Speaker: Shamik Gupta
Abstract: Nonequilibrium collective motion is ubiquitous in nature and often results in a rich collection of intriguing phenomena such as the formation of shocks or patterns, subdiffusive kinetics, traffic jams, and nonequilibrium phase transitions. These many-body features characterize transport processes in biology and soft condensed matter. Inspired by these applications, a wide class of lattice-gas models has recently been considered. Building on the celebrated Totally Asymmetric Simple Exclusion Process (TASEP) and a generalization accounting for the exchanges with a reservoir, I will discuss the qualitative and quantitative nonequilibrium properties of these model systems.
