摘要
The two-dimensional Yukawa pair potential represents a simple model for the interaction of charge-stabilized colloidal particles confined between two charged plates. Static and dynamical correlations in the liquid state of this model are calculated using Brownian dynamics simulations. In particular, the pair, triplet and orientational structure are discussed as well as dynamical quantities like particle diffusion and the time-dependence of the nearest-neighbour orientational correlation. It is found that the decay of nearest-neighbour orientation is non-exponential in time. Its relaxation occurs on a time scale that is much larger than a time typical for the crossover of the translational diffusion to the hydrodynamic regime.
