IS THERE AN IDEAL QUENCHING RATE FOR AN IDEAL GLASS

Using classical molecular dynamics simulations combined with the Voron oi tessellation we study, at very low temperature, the local structure in a model glass as a function of the quenching rate and the relaxati on time. The critical quenching rate below which crystallization effec ts become important is detected by the geometrical analysis. In fact w e show that this rate can be viewed as an ideal cooling rate since the study as a function of the aging time reveals a maximum stability of the glass structures quenched at that rate.
