Origin of Anomalous Diffusion and Non-Gaussian Effects for Hard Spheres: Analysis of Three-Time Correlations
Burkhard Doliwa, Andreas Heuer
Abstract
We present new simulation results on a hard sphere system at high densities. Using three-time correlations, we can account for the anomalous diffusion, which results from a homogeneous back-dragging effect. Furthermore, we calculate the non-gaussian parameter and connect it to the existence of dynamic heterogeneities.
