Horbenko E. The theory of atomic properties of compressed rare-gas crystals

This manuscript set oneself creation of methods of theoretical research of materials in extreme terms for the prediction of ground-state properties in hardness measurable regions; calculation of energy spectrums of the systems of quasi-particles in a solid and elastic properties of the studied systems at mechanical stressing. Subject of research is construction on first principle dynamic theory of lattices of crystals under pressure on the basis of nonempirical version of K.B.Tolpygo model. As the object of such theory it is most expedient to choose the rare-gas crystals (RGC). A scientific novelty consists in that first within the framework of K.B.Tolpygo model on the basis of nonempirical short-range potential away the dynamic theory of crystalline lattices of RGC is built in the wide interval of pressures. Quantitatively deformation of electronic shells is taken into account in the dipole approaching at р is not equals 0, which describes electron-phonon interaction. Practical application of RGC is related to possibility of the use them as coolants, working environment for the transmission of large hydrostatical pressure at low temperatures. The theoretical ground of possibility of receipt of new materials is given with new physical and chemical properties by high pressure.
