Molecular Dynamics of Colloidal binary mixtures in an electric field

We have studied a system of colloidal binary mixtures in an external electric field. The simulations were performed in the string fluid regime, low packing fraction, and high density regime under the influence of a strong electric field. In the dilute regime we studied the system structure for different concentrations and size ratios. For the high density regime we studied a 50:50 concentration with a size ratio or 1.2/1.0. We show the pair correlation function and diffusion coefficient. A partial phase diagram for the 50:50 concentration and 1.2/1.0 size ration is also presented.
