Abstract:

Colloidal dispersions are solid particles dispersed in continuous liquids. The particles may carry electric charge or neutral. The interaction, structure and dynamics of this system are very complicate and contains many interesting physics. In this talk I will give the current understandings of effective interactions between colloid particles, the liquid structure and phase transitions of colloids and, finally the short time and long time dynamics of colloids. Emphases will be given to the Monte Carlo evaluation of effective interactions, the pair distribution function and its calculation and experiment measurement, and the important effects of hydrodynamic interactions on the diffusion of colloid particles.
