On the Role of the Reference System in Perturbation Theory: An Augmented van der Waals Theory of Simple Fluids
Original language description
In this study, we show that the inclusion of a short-range part of the total attractive interaction into a reference system allows a natural extension of the traditional first-order perturbation theory of simple fluids to practically all thermodynamic states. This theory is applied to the thermodynamic functions and the liquid-vapor coexistence curve of the Lennard-Jones-like medium range Yukawa fluid and to the Sutherland fluid. Comparison with computer simulation data and the second-order Barker-Henderson perturbation theory is discussed.

Úloha referenčního systému v poruchové teorii: Zobecněná van der Waalsova rovnice jednoduchých kapalin
Czech description
Je ukázáno, že zahrnutí krátkodosahové části celkového potenciálu do referenčního systému umožňuje rozšířit použitelnost poruchového rozvoje 1. řádu na celou oblast termodynamických podmínek. Teorie je aplikována na Lennard-Jonesovu-Yukawovu tekutinu Sutherlandovu tekutinu. Výsledek je porovnán s teorií Barkera-Hendersona.
