Observation of vortex-antivortex pairing in decaying 2D turbulence of a superfluid gas

Abstract In a two-dimensional (2D) classical fluid, a large-scale flow structure emerges out of turbulence, which is known as the inverse energy cascade where energy flows from small to large length scales. An interesting question is whether this phenomenon can occur in a superfluid, which is invisc...
