Viscous growth in spinodal decomposition of the two-component Lennard-Jones model in three dimensions

The dynamics of phase separation of a two-component Lennard-Jones model in three dimensions is investigated by means of large scale molecular dynamics simulation. A systematic study over a wide range of quench temperatures within the coexistence region shows that the binary system reaches a dynamical scaling regime at late times during which the average domain size grows linearly with time in agreement with Siggiaʹs theoretical prediction and dimensional analyses of mode H.
