Abstract

The extended Zwergermethod of determining the chemical diffusion coefficient, for lattice gas conventional diffusion in equilibrium and superdiffusion in stationary state, is verified by Monte Carlo simulation of the centre-of-mass propogation. It has been found that the chemical diffusion coefficient for superdiffusion in one-dimensional, noninteracting lattice gas with the exclusion of double occupancy is concentration independent like in conventional diffusion. Moreover, it has been proved that (chemical) superdiffusion of uncorrelated particles is exactly described in this model by the Burgers nonlinear diffusion equation.
