Bose Condensates In Top Traps Exhibit Circulating Superfluid Flows, Juhao Wu, A. Widom
Allan Widom
For spin one atoms localized in a quadrapole magnetic field gradient, the atoms may be impeded from spin flipping their way out from the center of the trap by the application of a rotating uniform magnetic field. From a quantum mechanical viewpoint, such a trap for a Bose condensate is equivalent to having a superfluid in a rotating bucket. Vorticity is then expected to be induced in the condensate fluid flow without the application of any further external perturbations.
Bose Condensation And Superfluidity In Finite Rotating Bose Systems, Juhao Wu, A. Widom
Bose Condensation And Superfluidity In Finite Rotating Bose Systems, Juhao Wu, A. Widom
Allan Widom
There is a long standing problem about how close a connection exists between superfluidity and Bose condensation. Employing recent technology, for the case of confined finite Bose condensed systems in TOP traps, these questions concerning superfluidity and Bose condensation can be partially resolved if the velocity profile of the trapped atoms can be directly measured.
