The Effect of Static Disorder and Reactant Segregation on the A + B → Reaction

الأصل · EN

We derive the long-time behavior of the A + B → reaction in two dimensions, finding a universal exponent and prefactor in the absence of disorder. Sufficiently singular disorder leads to a (sub)diffusion-limited reaction and a continuously variable decay exponent. Pattern matching between the reactant segregation and the disorder is not strong enough to affect the long-time decay.
