Temperature Expansions in the Square-Shoulder Fluid I: the Wiener-Hopf Function
arXiv:1912.06574 · doi:10.1063/1.5142661
Abstract
We investigate the spatial structure of dense square-shoulder fluids. To this end we derive analytical perturbative solutions of the Ornstein-Zernike equation in the low- and high-temperature limits as expansions around the known hard sphere solutions. We then discuss the suitability of perturbative approaches in relation to the Ornstein-Zernike equation.
