Nonequilibrium fluctuations for a tagged particle in mean-zero one-dimensional zero-range processes
arXiv:math/0703226
Abstract
We prove a non-equilibrium functional central limit theorem for the position of a tagged particle in mean-zero one-dimensional zero-range process. The asymptotic behavior of the tagged particle is described by a stochastic differential equation governed by the solution of the hydrodynamic equation.
