Rate of Convergence to Equilibrium of Symmetric Simple Exclusion Processes
2000, v.6, Issue 1, 73-88
We give bounds on the rate of convergence to equilibrium of the symmetric simple exclusion process in $Z^d$. Our results include the existent results in the literature. We get better bounds and larger class of initial states via a unified approach. The method includes a comparison of the evolution of $n$ interacting particles with $n$ independent ones along the whole time trajectory.
