The reaction process A+A -> O in Sinai disorder

Abstract:

The single-species reaction-diffusion process A + A → O is examined in the presence of an uncorrelated, quenched random velocity field. Utilizing a field-theoretic approach, we find that in two dimensions and below the density decay is altered from the case of purely diffusing reactants. In two dimensions the density amplitude is reduced in the presence of weak disorder, yielding the interesting result that Sinai disorder can cause reactions to occur at an increased rate. This is in contrast ...
