Abstract
By means of molecular dynamics simulations we examine the aging process of a strong glass former, a silica melt modeled by the BKS potential. The system is quenched from a temperature above to one below the critical temperature, and the potential energy and the scattering function C(t_w,t+t_w) for various waiting times t_w after the quench are measured. We find that both qualitatively and quantitatively the results agree well with the ones found in similar simulations of a fragile glass former, a Lennard-Jones liquid.
