β¦ Synopsis
A statistical model is advanced for describing quantum turbulence in a superfluid system with Bose-Einstein condensate. Such a turbulent superfluid can be realized for trapped Bose atoms subject to either an alternating trapping potential or to an alternating magnetic field modulating the atomic scattering length by means of Feshbach resonance. The turbulent system is represented as a continuous mixture of states each of which is characterized by its own vorticity corresponding to a particular vortex.

Pairing leads to superfluidity in ultracold atomic gases, but this pairing can be frustrated when a population imbalance is present between the pairing partners. Here we investigate how vortices in the fermionic superfluid are affected by imbalance. We show that the vortex core radius is increased b
A recent hydrodynamic theory of superfluid turbulence in He II developed by the author is applied to the dynamics of a homogeneous vortex tangle. The theory contains five unknown macroscopic coefficients. These coefficients are determined by relating equations of the hydrodynamic theory to similar e
