Gauge-field rotation of 2D exciton Bose condensate in double quantum well by radial magnetic field

Abstract

Here it is shown that a radial magnetic field leads to rotation of a Bose condensed exciton cloud due to Aharonov-Bohm effect for an electron and a hole forming an exciton. As in the case of mechanical rotation of superfluids, rotation is accompanied by penetration of vortices into the cloud at some critical magnetic field. Penetration of vortices strongly affects the total intensity and the angular distribution of photoluminescence from the exciton cloud. This effect can be used for an effective experimental manifestation of exciton Bose condensation.
