Velocity of vortices in inhomogeneous Bose–Einstein condensates

We derive, from the Gross–Pitaevskii equation, an exact expression for the velocity of any vortex in a Bose–Einstein condensate, in equilibrium or not, in terms of the condensate wave function at the center of the vortex. In general, the vortex velocity is a sum of the local superfluid velocity, plu...
