Abstract

In order to improve our understanding of the glass transition we performed constant-energy molecular dynamics simulations on a soft-sphere system quenched from the liquid state to zero temperature. The temperature dependence of static (radial pair distribution function) and dynamic quantities (self-diffusion constant) has been investigated together with the temperature evolution of relevant structural properties deduced from the Delaunay-Voronoi tessellation of these samples. This study permits to shed new light on the structural freezing below the glass transition temperature and the evolution of the local structure through the transition.
