Abstract: The asymmetric exclusion process (ASEP) is a model of particles hopping along a one-dimensional lattice subject to open boundaries. The model is a non-equilibrium system with late time behaviour described by a unique stationary distribution. The relaxation rate to this distribution can be found by solving the Bethe Ansatz equations for the system and, from these solutions, the asymptotic behaviour of the relaxation rate has been calculated. We wish to extend these results to the reverse-biased phase - where the entry and exit of particles at the boundaries opposes the preferred direction of flow in the bulk.

In this talk, I'll describe how the structure of the Bethe roots change in the reverse-biased phase, and how this affects the asymptotic behaviour of the relaxation rate.
