Stochastic Dynamics of a Vortex Loop. Thermal Equilibrium
Sergey K. Nemirovskii, Luiza P. Kondaurova, Makoto Tsubota
We study stochastic behavior of a single vortex loop appeared in imperfect Bose gas. Dynamics of Bose-condensate is supposed to obey Gross-Pitaevskii equation with additional noise…

Cascade process of vortex tangle dynamics in superfluid He without mutual friction
Tsunehiko Araki, Makoto Tsubota
Recently the Kelvin wave cascade process in superfluid He at very low temperatures was discussed. In this mechanism, the dynamics of the waves on the vortex lines plays an impo…
