Mean field theory for the lattice gas

WebFIG. 40 Phase diagram for the half-filled FK model on a square lattice with the DCA (Hettler et al., 2000). The different lines correspond to different size clusters. The 2 × 2 cluster determines Tc from the ordered phase, while the other clusters employ a susceptibility analysis. Also included in the figure is the Ising model Tc for the effective spin model with … WebIn the lattice gas, a set of identical particles is assumed to represent the actual fluid. These particles are equipped with the appropriate momenta that will take them from one site of a regular lattice that spans the working domain to a neighboring site within a unit time interval.

WebIn this chapter, the mathematical description of the lattice gas is exposed in detail, as well as its mean-field and nearest-neighbor (Ising) versions. The mean-field (Kać) limit is also studied in a simple case, providing a rigorous justification of the van der Waals–Maxwell theory of condensation. WebA mean field theory is presented that for physically acceptable choices of the transition matrix gives an excellent prediction of the average occupation numbers. We introduce a factorizability condition, the violation of which gives rise to correlations that are reasonably well predicted by the mean field theory.
