Scaling behavior in the dynamics of a supercooled Lennard-Jones mixture

Condensed Matter 2009-10-22 v1

Abstract

We present the results of a large scale molecular dynamics computer simulation of a binary, supercooled Lennard-Jones fluid. At low temperatures and intermediate times the time dependence of the intermediate scattering function is well described by a von Schweidler law. The von Schweidler exponent is independent of temperature and depends only weakly on the type of correlator. For long times the correlation functions show a Kohlrausch behavior with an exponent β\beta that is independent of temperature. This dynamical behavior is in accordance with the mode-coupling theory of supercooled liquids.
