Vortex excitation in a stirred toroidal Bose-Einstein condensate
Vortex excitation in a stirred toroidal Bose-Einstein condensate
Motivated by the recent experiment [Wright et al., Phys. Rev. A 88, 063633 (2013)], we investigate formation of vortices in an annular BEC stirred by a narrow blue-detuned optical beam. In the framework of a two-dimensional mean field model, we study the dissipative dynamics of the condensate with parameters matched …
