Abstract

Thermodynamic equilibrium in a system of chaotic quantized vortices in superfluid helium in the case of a counterflow of nor-mal and superfluid components is considered. The cases of con-tinuum and discrete approaches are studied. The necessity for discretization arises already in the continuum approximation in order to calculate the contribution into the partition function aris-ing from various configurations of vortex loops. Obviously, the discretization is a very important element for numerical studies. In view of the complexity of the problem of stochastic dynamics of quantum vortex filaments under the action of random force, numerical simulation is the main tool to solve this problem. Some physical consequences of the results are discussed.
