Theory of electron transport in conducting systems of various dimensionality.

Main results:

1. Optical properties of polyvalent metals in infrared spectrum region were explained on the basis of electron-photon-phonon scattering effect suggested by the author.
2. The diffusion equation for electrons taking into account the phonon drag by electrons was derived. Its usage made it possible to explain and predict several effects of electron kinetics in metals (in collaboration with R.N. Gurzhi).
3. The static skin effect was predicted in a high magnetic field under the conditions of diffusive electron reflection from the metal surface.
4. The existence of almost free electrons in the HTSC model of the type of the Hubbard model with strong interaction between electron and disordered spin subsystems was shown.
5. It was shown that the reduction of the space dimensionality of the system from three to two essentially affects the electron relaxation processes. A general theory of transport phenomena in 2D conducting systems was constructed. A specific application of the theory was developed for the case of layered metallic compounds (in collaboration with R.N. Gurzhi and S.B. Rutkevich).
