Koval S. Construction and application the models in the microscopic metals theory.

The thesis is devoted to the construction of the hierarchy of fundamental model Hamiltonians in frames of microscopic many-electron metals theory. The electron-ion model Hamiltonian with nonlocal manyparticle interactions was obtained using the statistical operator averaging for the electron-nuclear model over the localized electron states. The transition to the ion metal model with effective manyparticle interactions was performed. A simple scheme for accounting short-range correlation in degenerated electron systems falling back on model interaction potentials such as the potential of a quantum packet is offered. The efficiency of the method is shown in calculating the characteristics of the electron liquid model in wide range of the coupling parameter. Application - calculation of metals characteristics.
