Vortex stream generation and enhanced propagation in a polariton superfluid

13 Jan 2020 Lerario Giovanni Maître Anne Boddeda Rajiv Glorieux Quentin Giacobino Elisabeth Pigeon Simon Bramati Alberto

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... (read more)
