We show that topological vortex pumping can be implemented for a dilute Bose–Einstein condensate confined in a magnetic time-averaged orbiting potential trap with axial optical confinement.
Vortex pump for a Bose-Einstein condensate utilizing a time-averaged orbiting potential trap
Contrary to earlier proposals for the vortex pump, we do not employ an additional optical potential to trap the condensate in the radial direction, but instead, this confinement is provided by the magnetic field throughout the pumping cycle.
Vortex pump for a Bose-Einstein condensate utilizing a time-averaged orbiting potential trap
II, we present the zero-temperature mean-field theory of the spin-1 BEC, describe the control cycle of the vortex pump, and discuss in detail the confinement of the condensate during the cycle.
Vortex pump for a Bose-Einstein condensate utilizing a time-averaged orbiting potential trap
The operation principle of the vortex pump is to control the spin degree of freedom of the condensate locally by slowly tuning the magnetic field B(r, t) in a cyclic manner such that the system acquires a fixed amount of vorticity per cycle [44–48].

Being coherent, the condensate itself can be treated with a Gross-Pitaevskii type equation coupled to a classical rate equation for the dynamics of an exciton reservoir , which appropriately models the incoherent excitations generated by nonresonant pumping that feed and interact with the condensate.
