Influence of Pressure on the Anharmonicity, and the Elastic Moduli, and their Temperature Dependences for Crystals with Pair Interactions
The classical form of the method of potentials was introduced to solid-state physics by Born. Born assumed that in some solids — for example, in ionic crystals — the interaction between particles (ions) can be described quite accurately as being of the pair type. Then, having specified the actual nature of the pair potential between ions, we cannot only calculate theoretically the equation of state but also predict many other properties of ionic crystals which are of great interest in the physics of high pressures and in geophysics.
