主 题:Bose-Einstein condensates synthetic magnetic field vortices
摘 要:The rotational properties of Bose-Einstein condensates in a synthetic magnetic field are studied by numerically solving the Gross-Pitaevskii equation and comparing the results to those of condensates confined in a rotating trap. It appears to be more difficult to add a large angular momentum to condensates spun up by the synthetic magnetic field than by the rotating trap. However, strength- ening the repulsive interaction between atoms is an effective and realizable route to overcoming this problem and can at least generate vortex-lattice-like structures. In addition, the validity of the Feynman rule for condensates in the synthetic magnetic field is verified.
