Computer simulation of liquid anisotropy. IV. Terms to second order in the external field of force

Abstract

The method of molecular dynamics computer simulation is extended to deal with liquid anisotropy induced by the interaction of an external electric (or magnetic) field with anisotropy of polarizability. The resulting Langevin functions follow accurately the analytical results of Kielich. The new method is applied to extract the details of rotation/translation interaction in a moving frame of reference. The appropriate first order correlation functions are much more oscillatory in the presence of a strong external field.
