Abstract: 

The zero range process with constant rate can be described as follows. Particles are distributed over the vertices of the d-dimensional torus. Each vertex has a clock that rings at rate one. When the clock of a (nonempty) vertex rings, a particle moves from that vertex to a randomly chosen neighbor. We obtain a tight bound for the spectral gap of this process, solving an open problem.
