| dc.description | We present a detailed numerical study of dynamical heterogeneities in the aging regime of a simple binary Lennard-Jones glass former. For most waiting times t_w and final times t, both the dynamical susceptibility χ_4(t,t_w) and the dynamical correlation length ξ_4(t,t_w) can be approximated as products of two factors: i) a waiting time dependent scale that grows as a power of t_w, and ii) a scaling function dependent on t,t_w only through the value of the intermediate scattering function C(t,t_w). We find that χ_4(t,t_w) is determined *only in part* by the correlation volume. | |
