Use of an enhanced bulk diffusion-based algorithm for phase separation of a ternary mixture.
Phase separation kinetics of two-dimensional ternary mixtures have been studied by means of a Monte Carlo approach. Standard Kawasaki kinetics are impractical to study the late stages of the segregation process at deep quenches. An extension of the accelerated algorithm for binary mixtures proposed by Marko and Barkema [Phys. Rev. E 52, 2522 (1995)] is presented to overcome this problem in a three-component system discretized with two coupled lattices. We study the domain growth and the scaling behavior over a wide range of quench depths. Computer performances of the Kawasaki and the accelerated schemes are compared.
