Dynamics of fluids

A critical question in diverse soft matter contexts is what role intermolecular forces play in the dynamics. We are working on a liquid state theory that explicitly includes the instability and chaos of molecular motion. We have found that measures of chaos carry the signatures of the well-known van der Waals picture of simple liquids and that chaos slows down at the liquid-vapor critical point.
