摘要：
We examine the phenomenon of dynamical heterogeneity in computer simulations of an equilibrium, glass-forming liquid. We describe several approaches for quantifying the spatial correlation of single-particle motion, and show that spatial correlations of particle displacements become increasingly long range as the temperature decreases toward the made-coupling critical temperature.
