Abstract

The non-Gaussianity behavior was studied, focusing on intermediate times. Molecular dynamics simulations of two different systems, Se and binary Lennard-Jones (LJ) gave strikingly the same law for the increase of the non-Gaussianity parameter (NGP), α2(t). A simple model revealed the prevalence of collective hopping of groups of particles.
