Dynamical Instability of a Nonequilibrium Exciton-Polariton Condensate
Dynamical Instability of a Nonequilibrium Exciton-Polariton Condensate
By imaging single-shot realizations of an organic polariton quantum fluid, we observe the long-sought dynamical instability of nonequilibrium condensates. We find an excellent agreement between the experimental data and a numerical simulation of the open-dissipative Gross-Pitaevskii equation, without performing any parameter fitting, which allows us to draw several important conclusions …
