Self-Organized PT-Symmetry of Exciton-Polariton Condensate in a Double-Well Potential

We investigate the dynamics and stationary states of a semiconductor exciton-polariton condensate in a double-well potential. We find that upon the population build-up of the polaritons by above-threshold laser pumping, coherence relaxation due to the phase fluctuations in the polaritons drives the system into a stable fixed point corresponding to a self-organized PT-symmetric phase.

Automated summary

The study shows that a semiconductor exciton-polariton condensate in a double-well potential, after being pumped by above-threshold laser, forms a self-organized PT-symmetric phase.
