Information × Registration Number 0200U003471, 0197U002478 , R & D reports Title Elementary excitation in superconducting, normal and spin low dimensional systems in magnetic field popup.stage_title Head Yermolayev O., Registration Date 15-05-2000 Organization Kharkov National University named after V.N. Karazin popup.description2 The spectrum and decrement of daming of the plasma and magnetoplasma waves in 2DEG with the electron impurity states are calculated. New methods for theoretical studies of the quantum spin-systems are proposed: a special perturbative approach developed for calculations of the tunnel splitting in the spin-systems like that in anisotropic paramagnets in magnetic field. The peculiarities of the quantum oscillations in a magnetic field in layered crystals and superlattices in an external magnetic field (the de Haas - van Alphen effect) below the upper critical field, i.e. in the vertex Abrikosov state are studied. A theory of local phono-plasmon, magnetoimpurity, spiral and quantum waves in layered conductors and superconductors is developed. Product Description popup.authors popup.nrat_date 2020-04-03 Close
