Zw. Gortel et al., DIFFUSION IN A GENERALIZED (DENSE AND MOBILE) MODEL OF A LATTICE-GAS, Physical review. B, Condensed matter, 52(23), 1995, pp. 16916-16919
Following a recent theory of diffusion in a lattice gas, we present a
generalization of the local mean-field approach to study diffusion in
a dense system in which particles are mobile. Our model reduces in wel
l-defined limits to the lattice gas and fluid models which we have pro
posed recently for an adsorbate diffusion on the surface of a metal.
