Stability and spatial coherence of nonresonantly pumped exciton-polariton condensates
Stability and spatial coherence of nonresonantly pumped exciton-polariton condensates
We investigate the stability and coherence properties of one-dimensional exciton-polariton condensates under nonresonant pumping. We model the condensate dynamics using the open-dissipative Gross-Pitaevskii equation. In the case of spatially homogeneous pumping, we find that the instability of the steady state leads to significant eduction of the coherence length. We consider …
