A lattice-gas model of microemulsions

We develop a lattice gas model for the non-equilibrium dynamics of microemulsions. Our model is based on the immiscible lattice gas of Rothman & Keller, which we reformulate using a microscopic, particulate description so as to permit generalization to more complicated interactions, and on the prescription of Chan & Liang for introducing such interparticle interactions into lattice gas dynamics. We present the results of simulations to demonstrate that our model exhibits the correct phenomenology, and we contrast it with both equilibrium lattice models of microemulsions, and to other lattice gas models.
