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.

WebNov 28, 2024 · The Bragg-Williams free energy is used to incorporate nearest-neighbor interactions into the lattice gas model of a solvent-free ionic liquid near a planar electrode. We calculate the differential capacitance from solutions of the mean-field consistency relation, arriving at an explicit expression in the limit of a weakly charged electrode. WebS.
