Abstract

Collective diffusion of lattice gases in linear chains with site-energy disorder is studied. The mean-field theory of the diffusivity is formulated in terms of effective transition rates. An exact expression is derived for the diffusion coefficient of single vacancies, in the limit of large particle concentration. Numerical simulations were performed and compared with the predictions of the mean-field theory and a correction to it.
