Effective attractive polariton-polariton interaction mediated by the exciton reservoir
arXiv:1403.3543 · doi:10.1103/PhysRevB.90.035413
Abstract
We present a mechanism to endow the polariton gas with attractive interactions. The scheme relies on an exciton reservoir, which can be formed even if excitons lie outside of the light-cone. Such an attractive interaction should open new routes in the physics of quantum fluids, that we illustrate with a simple but nontrivial application whereby the polariton condensate enters the self-oscillation regime powered by the attraction from the reservoir. This results in pulsed emission in the GhZ regime.
