| dc.description.abstract | We present a theory of excitonic quantum Hall droplet (EXQHD) at filling factor nu=2 in a self-assembled quantum dot (SAD) subject to strong perpendicular magnetic field B. Using exact diagonalization technique we determine the ground and excited states, the stability against spin flips, and the optical emission spectrum of the nu=2 EXQHDs. In contrast with one-component electronic droplets, the singlet-singlet nu=2 EXQHD is found to be intrinsically correlated, and stable even in high magnetic fields due to the neutrality of exciton. The characteristic spin related emission spectrum and its magnetic field evolution from the EXQHD are predicted. | en_US |
