Résumé
Phys. Rev. Lett. 78, 4581 (1997) Using molecular dynamics simulations we study the out of equilibrium dynamic
correlations in a model glass-forming liquid. The system is quenched from a
high temperature to a temperature below its glass transition temperature and
the decay of the two-time intermediate scattering function C(t_w,t+t_w) is
monitored for several values of the waiting time t_w after the quench. We find
that C(t_w,t+t_w) shows a strong dependence on the waiting time, i.e. aging,
depends on the temperature before the quench and, similar to the case of spin
glasses, can be scaled onto a master curve.
