Models of Mixed Matter

The review considers statistical systems composed of several phases that are intermixed in space at mesoscopic scale and representing a mixture components microscopic objects. These types mixtures should be distinguished from the Gibbs phase mixture, where system is filled by macroscopic pieces phases. description rather simple, consisting consideration pure separated surface, whose contribution becomes negligible thermodynamic limit. properties mixtures, scale, principally different. emphasis on matter with mixed scale. Heterogeneous materials ubiquitous nature. A general theory such presented illustrated condensed models. objects clustering quark-hadron matter.
