Temperature Expansions in the Square Shoulder Fluid II: Thermodynamics
arXiv:1912.06580 · doi:10.1063/1.5142662
Abstract
In a companion paper, we derived analytical expressions for the structure factor of the square-shoulder potential in a perturbative way around the high- and low-temperature regimes. Here, various physical properties of these solutions are derived. In particular, we investigate the large wave number sector, and relate it to the contact values of the pair-correlation function. Then, thermoelastic properties of the square-shoulder fluids are discussed.
