Abstract

We investigate theoretically the Bose-Einstein condensation of trapped magnetoexcitons in a two-layered system with one layer containing electrons and the other layer containing holes. We have studied the spatial variations of the condensate density in the droplet of electrons and holes. We find that the shape of the electron and hole densities may change due to the competition between repulsive electron-electron/hole-hole interaction and confinement potential of the trap. Our mean-field calculations show that when the confinement strength is strong enough the condensate density is peaked at the edge of the droplet, and as the confinement strength weakens the condensate density displays one inner peak and another peak at the edge. For much weaker confinement potential, the condensate density may display one broad peak.
