Achieving ultracold Bose-Fermi mixture of 87Rb and 40K with dual dark magnetic-optical-trap
文献摘要：
We demonstrate that dual dark magnetic-optical-traps(MOTs)have great importance in the two-species 87 Rb and 40K mixture compared with dual bright MOTs.The dark MOT has a little improvement in the trapping of single-species 87 Rb or 40K gases compared with bright MOT.For the case of loading two-species 87Rb and 40K simultaneously,the improvement of 40K in the dual dark MOTs is mainly from the reduction of light-assisted collision losses.The dual dark MOTs employ a pair of conical lenses to produce the hollow beam for repump laser with high efficiency.The number and density of 87 Rb and 40 K atoms after evaporative cooling in the hybrid magnetic trap with dark MOT loading are compared with those in bright MOT.The atoms with large number and high density make it easier to realize the quantum degenerate of Bose-Fermi mixture.
