Polarization and Aharonov-Bohm oscillations in quantum-ring magnetoexcitons
Polarization and Aharonov-Bohm oscillations in quantum-ring magnetoexcitons
We study interaction and radial polarization effects on the the absorption spectrum of neutral bound magnetoexcitons confined in quantum-ring structures. We show that the size and orientation of the exciton's dipole moment, as well as the interaction screening, play important roles in the Aharonov-Bohm oscillations. In particular, the excitonic absorption …
