First-order quantum corrections to depolarized interaction-induced light-scattering spectral moments: Molecular-dynamics calculation

Abstract

A method for calculating the first quantum corrections to the moments of depolarized interaction-induced light-scattering spectra has been applied for a many-body system. Classical averages have been evaluated via the molecular-dynamics simulation technique. The numerical evaluation of the first quantum correction to a "static" and a "dynamical" property is given for simple fluids. We also find that systems which are usually considered classical from the point of view of static properties may exhibit a non-negligible quantum contribution to their "dynamical" behavior.
