Semiclassical statistical mechanics of two-dimensional fluid mixture of hard disks

Abstract

High-temperature expansions for the density-independent part of the radial distribution function and the first-order density correction to it are obtained for a two-dimensional binary mixture of hard disks. The ‘‘excess’’ quantum corrections to the second and third virial coefficients and excess free energy are also discussed. It is found that the ‘‘excess’’ quantum effect depends on the concentration and the diameter radio.
