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…
