Kinetics of spinodal decomposition in the Ising model with dynamic lattice liquid (DLL) dynamics

Abstract The phase separation dynamics in two-dimensional binary mixtures is studied by means of a dynamic lattice liquid (DLL) model. In contrast to other methods, a simulation based on a DLL model works properly for dense systems characterized by full occupation of the lattice sites. The DLL model is a base for the first parallel algorithm which takes into account coincidences of elementary molecular movements resulting in a local cooperative structural transformation. It permits observation of a phase separation process in a system where movements of particles are highly correlated. We have investigated the influence of the proposed dynamics on a critical temperature value of TC, the domain growth and diffusion above and below TC.
