Internal and external polarization memory loss in single quantum dots

Abstract

We study exciton spin relaxation in single semiconductor quantum dots using non-linear resonant optical control. Experiments reveal two distinct channels for spin relaxation, external and internal, ruling out universal freezing of exciton spin relaxation.
