NONEQUILIBRIUM SPATIAL CORRELATIONS OF REAGENTS IN MODEL REACTION-DIFFUSION SYSTEM

The mesoscopic description of systems with chemical reactions predicts that if the detailed balance condition is not satisfied then the none quilibrium spatial correlations between concentrations of reactants ma y appear. The present work is concerned with molecular dynamics simula tions of these correlations. The correlations appearing in a stationar y state of a multicomponent chemical system and in a time dependent st ate of an ''enzymatic'' reaction are studied. Nonequilibrium correlati ons between reactants observed in simulations are compared with result s of theory based on the master equation for a spatially distributed s ystem.
