Predicting phase transition possibility pressure in solids: A semi-classical possibility

Abstract

This is a short review of the physical ideas, algorithm for calculations of the phase transition pressure, and some results of a semi-classical theory of the behavior of materials under high pressure proposed by Savić and Ka[sbreve]anin. It is based on the Coulomb interaction, supplemented by a microscopic selection rule and a set of experimentally founded postulates. The theory hasbeen applied to cases ranging from DAC experiments to the calculation of models of planetary internal structure.
