Abstract

We present a general method for constructing effective one particle dynamics in colloidal systems, which results from a contraction of the description of colloidal mixtures based on the many particles Langevin and Smoluchowski equations. In order to illustrate its applicability, we calculate the long-time self-diffusion coefficient of charged particles, as well as its electrophoretic mobility. The accuracy of our approaches is pointed out by comparison with available experimental data.
