Self-organized PT-symmetry of exciton-polariton condensate in a double-well potential

TL;DR

This paper explores how a semiconductor exciton-polariton condensate in a double-well potential self-organizes into a PT-symmetric phase driven by coherence relaxation and phase fluctuations, revealing new stable states.

Contribution

It demonstrates the emergence of a self-organized PT-symmetric phase in exciton-polariton condensates due to coherence relaxation effects.

Findings

Identification of a self-organized PT-symmetric phase

Coherence relaxation drives the system into a stable fixed point

Observation of phase fluctuation effects on condensate dynamics

Abstract

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 of the polaritons drives the system into a stable fixed point corresponding to a self-organized PT-symmetric phase.
