Path integral Monte Carlo study of the internal quantum state dynamics of a generic model fluid

摘要

We study the quantum dynamics of a generic model fluid with infernal quantum states and classical translational degrees of freedom in two, spatial dimensions. The path integral Monte Carlo data for the imaginary lime correlation functions are presented and analyzed by the maximum entropy method, A comparison of the frequency distribution with those of a mean field approximation and virial expansion shows goad agreement at high and low densities, respectively.
