MODE-COUPLING THEORY AND TAILS IN CA FLUIDS

After a summary of important effects of mode-coupling theory in continuous fluids, the theory is extended to CA fluids and the long-time tails calculated for the velocity correlation function and for the stress-stress correlation function, including the spurious contributions from the staggered momentum densities. At finite densities the Fermi statistics strongly suppresses the long-time singularities arising from two fluid modes, but not those from tagged particle diffusion.
