The mesoscopic description of a system with chemical reactions predicts that if the detailed balance condition is not satisfied then the nonequilibrium spatial correlations between concentrations of reactants may appear. The present work is concerned with the dynamics of their growth. We assume...

The mesoscopic description of a system with chemical reactions predicts that if the detailed balance condition is not satisfied then spatial correlations between concentrations of reactants may appear. In this paper we use the molecular dynamics technique for reactive hard spheres in order to...

The k-dependent hydrodynamic fluctuations for binary classical fluids are discussed. The aim of this paper is to give the microscopic basis for the phenomenological formulation of hydrodynamics of binary fluids which was explored by the present author. The generalized Langevin equation formalism...

Starting from the Langevin equation a nonlinear evolution equation describing the mean square distance of initially close tagged particles in a turbulent medium is obtained. The equation is the same as that derived for a turbulent plasma by Misguich and Balescu using renormalized kinetic theory....

We show that a stochastic process on a complex plane can simulate decay from a metastable state. The simplest application of the method to a model in which the approach to equilibrium occurs through transitions over a potential barrier is discussed. The results are compared with direct numerical...

In this paper we show how the methods of statistical physics may be applied to describe the nonequilibrium effects in systems with thermally activated reactions. A special attention is given to systems with multiple reactions, in which such effects are more important then in systems with a...
