DYNAMICS AND EFFECTIVE THERMODYNAMICS OF A MODEL STRUCTURAL GLASS (J PHYS CONDENS MATTER, VOL 5, PG L349, 1992)

We use Monte Carlo methods to investigate, a purely dynamical model fo r structural glasses. We observe stretched exponential decays of the e quilibrium autocorrelation function and measure the late-time relaxati on times tau. These diverge with temperature following a Vogel-Fulcher law. We also study systems which are quenched deeply and then re-heat ed. This gives a peak in the effective specific heat with properties m atching those of the glass transition. The model thus reproduces the m ain phenomenology of glasses and the glass transition.
