Finite-temperature dynamics of vortices in Bose-Einstein condensates
Finite-temperature dynamics of vortices in Bose-Einstein condensates
We study the dynamics of a single and a pair of vortices in quasi two-dimensional Bose-Einstein condensates at finite temperatures. We use the stochastic Gross-Pitaevskii equation, which is the Langevin equation for the Bose-Einstein condensate, to this end. For a pair of vortices, we study the dynamics of both the …
