Nucleation and kinematics of vortices in stirred Bose Einstein condensates
Jonas Rønning, Luiza Angheluta
We apply the Halperin-Mazenco formalism within the Gross-Pitaevskii theory to characterise the kinematics and nucleation of quantum vortices in a two-dimensional stirred Bose Einst…

Classical analogies for the force acting on an impurity in a Bose-Einstein condensate
Jonas Rønning, Audun Skaugen, Emilio Hernández-García +2
We study the hydrodynamic forces acting on a small impurity moving in a two-dimensional Bose-Einstein condensate at non-zero temperature. The condensate is modelled by the damped-G…
