Ebook "Electron–phonon interaction in conventional and unconventional superconductors" describes the development and scientific implementation of a new experimental method that puts this old problem into an entirely new light. The nominee has made major contributions to the development and implementation of a new experimental method that enhances the resolution of spectroscopic experiments on dispersive lattice-vibrational excitations (the "glue" responsible for Cooper pairing of electrons in conventional superconductors) by more than two orders of magnitude.

In this work, the temperature dependence of the anharmonic X-ray absorption fine structure (XAFS) and thermodynamic properties of the crystalline silicon (c-Si) have been investigated. The thermodynamic parameters are derived from the influence of the absorbing and backscattering atoms of all their nearest neighbors in the crystalline lattice with thermal vibrations.

The moment method in the statistical dynamics is used to study the thermodynamic properties of metals taking into account the anharmonicity effects of the lattice vibrations. The effective pair potentials work well for the calculations of metals. For obtaining better agreement of the thermodynamic quantities of metals like Nb, the many body potentials derived from the microscopic electronic theory are used. The theoretical calculations of the thermodynamic properties are in good agreement with the corresponding experimental results.
