I: Zero-range processes." The Annals of Probability 27, no. 1: 325-360.0091-1798http://nrs.harvard.edu/urn-3:HUL.InstRepos:32710645Under mild assumptions we prove that for any local function uu the decay rate to equilibrium in the variance sense of zero range dynamics on dd-dimensional integer lattice is Cut−d/2+o(t−d/2)Cut−d/2+o(t−d/2). The constant CuCu is computed explicitly.en-USJournal Article2017-05-1810.1214/aop/1022677265
