Investigation of Locallyanharmonic Models of Structuralphase Transitions


In the context of description of the structural phase transition in solids, the anharmonic potential eeecting on the ion in the crystal lattice is selected in the form that in addition to quadric includes cubic anharmonicity, thus possessing more general non-symmetrical form, and in the symmetrical form with the Gaussian barrier. The approach based on the… (More)
