Bose-Einstein condensation of two-dimensional magnetoexcitons on the superposition state and excited Landau levels

Abstract

The Bose-Einstein Condensation (BEC) of the two-dimensional magnetoexcitons on the superposition state, as well as on the excited Landau levels, is studied. The superposition of two excitonic states formed by electron and hole on the lowest Landau levels (0, 0) and on the first excited Landau levels (1, 1) was considered. The generalized Bogoliubov u-v transformation was deduced. The criterion for the exciton concentration was established. These questions will be studied below.
