TY - JOUR ID - KobGlotzerPRL1997 L3 - citeulike-article-id:1304861 N2 - We present the results of a molecular dynamics computer simulation study in which we investigate whether a supercooled Lennard-Jones liquid exhibits dynamical heterogeneities. We evaluate the non-Gaussian parameter for the self part of the van Hove correlation function and use it to identify “mobile” particles. We find that these particles form clusters whose sizes grow with decreasing temperature. We also find that the relaxation time of the mobile particles is significantly shorter than that of the average particle; and that this difference increases with decreasing temperature.
