Phase behavior of hard-core lattice gases: A fundamental measure approach

Abstract

The extension of FMT was applied to lattice models to study two systems already treated in the literature: the two-dimensional lattice gas with first and second neighbor exclusion on a square lattice, and the binary mixture of parallel hard cubes, with edge-lengths σL=6 and σS=2 on a simple cubic lattice. For both systems, a systematic way of using the theory in order to perform a complete calculation of the bulk phase diagrams was shown.
