The polarization dependence of quantum beats from the A-exciton and the B-exciton in a GaN sample of exceptional quality is studied with four-wave mixing experiments. When changing the incident polarizations from collinear to crossed linear, a π-phase shift of the beats is observed while the decay rate remains unchanged. This confirms previous theoretical predictions.
