Computation of transport coefficients and the dynamical structure factor of Xe in the presence of long-range three-body interactions

Abstract

The importance of the three-body dispersion interaction (Axilrod-Teller potential) in liquid Xe near its triple point is investigated by numerical simulations. Although large for the heavy rare gas Xe, its effect on collective dynamical properties such as the dynamical structure factor and transport coefficients is very small. When used in conjunction with an accurate pair potential, good agreement is obtained with experiment for both the pressure and transport coefficients.
