Hydrodynamics of confined colloidal fluids in two dimensions.

Abstract:

We apply a hybrid molecular dynamics and mesoscopic simulation technique to study the dynamics of two-dimensional colloidal disks in confined geometries. We calculate the velocity autocorrelation functions and observe the predicted t;{-1} long-time hydrodynamic tail that characterizes unconfined fluids, as well as more complex oscillating behavior and negative tails for strongly confined geometries. Because the t;{-1} tail of the velocity autocorrelation function is cut off for longer times i...
