Kinetics of phase separation in a dilute short-ranged square-well system: a molecular dynamics study

We report on a molecular simulation study of the phase separation in a dilute short-ranged square-well system. The phase diagram of model displays solid-fluid equilibrium, with a metastable fluid-fluid separation. Equilibrium fluid configuration are quenched along the isochore at a sequence of temperatures and followed during the time evolution. We present the clear evidence of the metastable fluid-fluid separation, of the homogeneous crystallization and of the kinetically arrested gel. We also discuss the relevance of our simulation to the ``crystallization slot''.
