Quantum turbulence in superfluids with wall-clamped normal component

Abstract

In Fermi superfluids, like superfluid 3He, the viscous normal component can be considered to be stationary with respect to the container. The normal component interacts with the superfluid component via mutual friction which damps the motion of quantized vortex lines and eventually couples the superfluid component to the container. With decreasing temperature and mutual friction the internal dynamics of the superfluid component becomes more important compared to the damping and coupling effects from the normal component. This causes profound changes in superfluid dynamics: the temperature-dependent transition from laminar to turbulent vortex motion and the decoupling from the reference frame of the container at even lower temperatures.
