Quantifying Spatially Heterogeneous Dynamics in Computer Simulations of Glassforming Liquids
Sharon C. Glotzer, Claudio Donati
Abstract
We examine the phenomenon of dynamical heterogeneity in computer simulations of an equilibrium, glass-forming liquid. We describe several approaches to quantify 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 mode coupling critical temperature.
