The research object is conductive and superconducting nanosystems placed in a dc magnetic field. The aim is an analytical and numerical study of physical magnetotransport phenomena in quasi-two-dimensional nanofilms and layered superconductors. In particular, the physical quantities like the Coulomb drag resistance of a two-layer system, the focal length and waist for a laser beam, are planned to be analytically calculated, as well as the dependences of these quantities on parameters such as temperature, magnetic field, degree of nonlinearity, etc are aimed to be determined. As a result of these theoretical studied, new fundamental knowledge about the specified conducting and superconducting nanosystems are obtained and the directions and ways of the further investigations will be found. The main tasks are: - Elaborate a hydrodynamic model of a non-Fermi electron liquid that is formed in a clean quasi-two-dimensional conductive nanofilm. - Develop a model of the propagation of terahertz laser radiation in a layered superconductor in the presence of a dc magnetic field. - Derive and solve the Navier-Stokes equation for a two-layer system in the presence of a magnetic field. - Derive and solve the equations for the amplitude, phase and curvature of the laser beam front as it passes the "tail" of the Josephson vortex. - Calculate the Coulomb drag resistance and investigate its dependence on the parameters, in particular, on the magnitude of the magnetic field. - Calculate the focal length and waist of the transmitted beam and study the dependencies of these values on the parameters, in particular, the magnitude of the magnetic field and the frequency of the laser beam.
