Classical turbulence is hard enough to understand. How about turbulence in a quantum fluid such as superfluid helium?
Is there any difference?
There is a nice viewpoint Reconnecting to superfluid turbulence which is a commentary on the 2008 PRL Velocity Statistics Distinguish Quantum Turbulence from Classical Turbulence.
A key difference between the quantum and classical case concerns the reconnection of vortices.
