The Asymmetric Exclusion Process revisited: Fluctuations and Dynamics in the Domain Wall Picture

Abstract

We investigate the total asymmetric exclusion process by analyzing the dynamics of the shock. Within this approach we are able to calculate the fluctuations of the number of particles and density profiles not only in the stationary state but also in the transient regime. We find that the analytical predictions and the simulation results are in excellent agreement.
