Metastable bound states of the two-dimensional quasi–bimagnetoexcitons

Abstract

The interactions and the bound states of the two-dimensional (2D) magnetoexcitons with different wave vectors k were considered. First of all the case of two magnetoexcitons with wave vectors k  0 was investigated. Their gyration points coincide, their Landau quantization orbits overlap and such magnetoexcitons with electrons and holes situated on the lowest Landau levels look as neutral compound particles. The Coulomb interaction between them vanishes. Only the influence of the excited Landau levels (ELLs) and of the Rashba spin-orbit coupling (RSOC) can change the situation.
