Spontaneous rotating vortex rings in a parametrically driven polariton fluid
Spontaneous rotating vortex rings in a parametrically driven polariton fluid
We present the theoretical prediction of spontaneous rotating vortex rings in a parametrically driven quantum fluid of polaritons – coherent superpositions of coupled quantum well excitons and microcavity photons. These rings arise not only in the absence of any rotating drive, but also in the absence of a trapping potential, …
