Structural phase transitions in the strongly coupled systems with isotropic potentials

Summary form only given. Study of structural phase transitions is of significant interest with fundamental point of view and, at present time, it is a subject of the intensive theoretical and experimental researches in various areas of physics. Such transitions are the phase transformations (of configuration, topology, polymorphic, or solid-liquid transitions) in strongly coupled systems, which consist in a structure reorganization of these systems and, in most cases, lead to a change of their symmetry type. Besides fundamental aspects, study of structural phase transitions is of special interest for development of nano- and micro- technologies, and of covers and materials with the defined properties.
