Bottleneck crossover between classical and quantum superfluid turbulence
Bottleneck crossover between classical and quantum superfluid turbulence
We consider superfluid turbulence near absolute zero of temperature generated by classical means, e.g., towed grid or rotation but not by counterflow. We argue that such turbulence consists of a polarized tangle of mutually interacting vortex filaments with quantized vorticity. For this system, we predict and describe a bottleneck accumulation …
