The goal of this monograph is to highlight the many-body and complex character of some
metal-oxide heterostructure problems and to discuss recent theoretical advances in this field
achieved by the authors. The concept of a self-consistent field based on the diagram method of
the time-dependent perturbation theory is introduced and the following aspects of the theory
applications are discussed: metal-insulator phase transition for a half-filled electron band; impact
of the electron-phonon interaction on the excitation spectrum and damping in a narrow-band
electron subsystem; possible mechanism of the high-temperature superconductivity in cuprates
and specific magnetic and resistive properties of manganites, charge transport and resistive
bipolar switching phenomenon in oxide-based heterostructures.
For researchers working in the field of solid-state physics, PhD and master’s students at
physical faculties of universities and research institutions.
