Vortex stream generation and enhanced propagation in a polariton superfluid
arXiv:2001.04434 · doi:10.1103/PhysRevResearch.2.023049
Abstract
In this work, we implement a new 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 novel technique is a powerful tool for the controlled generation and propagation of quantum turbulences and paves the way to the study of the hydrodynamic of quantum turbulence in driven-dissipative 2D polariton systems.
