Abstract:
Orientational correlations of rodlike colloidal particles interacting via a two-site Yukawa potential are investigated using Brownian dynamics computer simulations. It is found that the orientational relaxation proceeds in three different regimes: very short-time regime, diffusive and long-time nondiffusive. An influence of particle concentration, the one-particle diffusion tensor, and particle elongation on these regimes is discussed.
