Turbulent phenomena are among the most striking effects that both classical and quantum fluids can exhibit. While classical turbulence is ubiquitous in nature, the observation of quantum turbulence requires the precise manipulation of quantum fluids such as superfluid helium or atomic Bose-Einstein condensates. In this work we demonstrate the turbulent dynamics of a 2D quantum fluid of exciton-polaritons, hybrid light-matter quasiparticles, both by measuring the kinetic energy spectrum and showing…

Inverse energy cascade in two-dimensional quantum turbulence in a fluid of light

Turbulence in quantum fluids has, surprisingly, a lot in common with its classical counterparts, including cascade of excitations across length scales [1]. In two dimensions, the existence of a range

Spectral analysis for compressible quantum fluids

Turbulent fluid dynamics typically involves excitations on many different length scales. Classical incompressible fluids can be cleanly represented in Fourier space enabling spectral analysis of energy
