Spontaneous Symmetry Breaking in a Polariton and Photon Laser
Spontaneous Symmetry Breaking in a Polariton and Photon Laser
We report on the simultaneous observation of spontaneous symmetry breaking and long-range spatial coherence both in the strong and the weak-coupling regime in a semiconductor microcavity. Under pulsed excitation, the formation of a stochastic order parameter is observed in polariton and photon lasing regimes. Single-shot measurements of the Stokes vector …
