Deskripsi

In this work we implement an experimental configuration which exploits the specific properties of the optical bistability exhibited by the polariton system and we demonstrate the generation of a superfluid turbulent flow in the wake of a potential barrier. The propagation and direction of the turbulent flow are sustained by a support beam on distances an order of magnitude longer than previously reported. This technique is a powerful tool for the controlled generation and propagation of quantum turbulence and paves the way for the study of the hydrodynamics of quantum turbulence in driven-dissipative two-dimensional polariton systems.
