Abstract
Molecular-dynamics simulations of homogeneous crystalline nucleation in systems of 1300 Lennard-Jones particles have been performed as a function of quench depth. The time lag between the time of formation of the critical nucleus and the time of release of latent heat is observed to be a nonmonotonic function of quench depth. The increase of the time lag for deep quenches is interpreted as evidence for critical slowing down and the influence of a "pseudospinodal."
