Partially Asymmetric Exclusion Process with Open Boundaries
Abstract
Exclusive diffusion on a one-dimensional lattice is studied. In the model particles hop stochastically into both directions with different rates. At the ends of the lattice particles are injected and removed. The exact stationary probability measure is represented in form of a matrix product as a generalization of the solution given by Derrida et al \cite{dehp} for the fully asymmetric process. The phase diagram of the current on the infinite lattice is obtained. Analytic expressions for the current in the different phases are derived. The model is equivalent to a -Heisenberg chain with a certain type of boundary terms the ground state of which corresponds to the stationary solution of the master equation.
