Abstract
We have carried out Brownian dynamics simulations to measure the self-diffusion of charged colloids in the presence of an oscillating shear flow. We observe that in the two directions perpendicular to the shear velocity direction, the diffusion constant increases monotonically with the shear rate γ. We also find a slight layering along the shear direction. Our results are compared to the forced Rayleigh scattering experiments of Qiu et al. [Phys. Rev. Lett. 61, 2554 (1988)].Keywords
