Dynamic computer simulation of concentrated hard sphere suspensions II. Re-analysis of mean square displacement data

Abstract : In view of recent theoretical results by Cichocki and Felderhof we reevaluate previously published simulation data for the mean square displacement of a particle in a hard sphere suspension without hydrodynamic interactions. This new evaluation is consistent with the theoretically predicted algebraic long-time tails. We observe better agreement for dense systems and obtain values for the relaxation time almost twice as large as previously.
