Lattice simulations decomposition

In Fig. 12 we present some results of MFKEbbased simulation of spinodal decomposition with the vacancy-mediated exchange mechanism. We use the same 2D model on a square lattice with the nearest-neighbor interaction and Fp = 0 as in Refs., ...

The technique to study phase coexistence via MD by simulating phase separation kinetics in the MVT ensemble until equilibrium is established [234] becomes cumbersome near critical points, and in any case it requires the simulation of very large systems over a large simulation time. In addition, this method is hardly feasible when the model systems contains long polymers - their diffusion simply is too slow [5, 6, 8, 9, 31]. Experience with the simulation of spinodal decomposition in lattice models of polymer mixtures [9, 180, 241] shows that only the early stages of phase separation are accessible, meaning that the method is unsuitable for studying the equilibrium states of well phase-separated systems.
