Chaotic Lattice - Gas Model
V. I. Yukalov, E. P. Yukalova
Abstract
A nonuniform system is considered consisting of two phases with different densities of particles. At each given time the distribution of the phases in space is chaotic: each phase filling a set of regions with random shapes and locations. A chaotic diffusion process intermixes these regions by varying their shapes and locations in a random way. To investigate the statistical properties of such a system, it is exemplified by a lattice-gas model. Conditions are analysed when this chaotic lattice-gas model can become thermodynamically more stable than the usual model describing a pure one-phase system.
