Abstract

Monte Carlo simulations are used to study various properties of a new lattice model of microemulsions. In particular, we calculate the critical exponent β of the order parameter (water concentration) and the correlation length exponent ν, and find them to be in excellent agreement with those of the 3D Ising model, and also in agreement with the experimental measurements. However, when the same exponents are calculated for the microemulsions in a porous medium, they do not agree with those of either the dilute or the random-field Ising model.
