In particular, the analytical calculation of quantities characterizing the Coulomb resistance of a two-layer system, the coefficient of transparency and focal length for a laser beam is planned, as well as the manifestation of dependences of these quantities on parameters such as temperature, magnetic field, degree of nonlinearity, electroneutrality. etc. As a result of these theoretical researches new fundamental knowledge about the specified conducting and superconducting nanosystems and the established directions and ways of the further researches will be received. To achieve this goal, the following tasks were formulated: ◦ Construct a hydrodynamic model of a non-Fermi electron fluid formed in a pure quasi-two-dimensional conductive nanofilm. ◦ Build a model of the propagation of terahertz laser radiation in a layered superconductor in the presence of a constant magnetic field. ◦ Compose and solve the Navier-Stokes equation for a two-layer system in the presence of a magnetic field. ◦ Compose and solve the equation for the amplitude, phase and curvature of the front of the laser beam 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 temperature and the magnitude of the magnetic field. ◦ Calculate the coefficient of transparency and focal length and investigate the dependences of these values ​​on the parameters, in particular, on the magnitude of the magnetic field and the frequency of the laser beam. popup.nrat_date 2024-12-09 Close
