Rezumat

The Rashba spin-orbit coupling (RSOC) in the case of two-dimensional (2D) electrons and holes in a strong perpendicular magnetic field is studied. The spinor-type wave functions are characterized by different numbers of Landau levels in different spin projections. For electrons, they differ by 1 as was established earlier by Rashba [1], whereas for holes they differ by 3. Two lowest electron states and four lowest hole states of Landau quantization give rise to eight 2D magnetoexciton states. The exchange electron-hole interaction in the frame of these states is investigated.
