Turbulent regime investigation in quantum fluids of light

Abstract
The observation of turbulent regimes in quantum fluids is receiving renewed interest thanks to the ability to manipulate with a high degree of control quantum systems such as superfluid helium or atomic Bose–Einstein condensates. We discuss the turbulent dynamics of a two-dimensional quantum fluid of exciton–polaritons, hybrid light–matter quasiparticles, both by measuring the kinetic energy spectrum and showing the onset of vortex clustering. These results contribute to the investigations of quantum turbulence in two-dimensional fluids, a relatively young research field.
