Hysteresis in quantized vortex shedding
arXiv:1405.4577 · doi:10.1103/PhysRevA.90.013612
Abstract
It is shown using numerical simulations that flow patterns around an obstacle potential moving in a superfluid exhibit hysteresis. In a certain velocity region, there is a bistability between stationary laminar flow and periodic vortex shedding. The bistability exists in two and three dimensional systems.
