论文摘要
我们已经观察到69 $^{41} $ k-$^6 $ li interpecies feshbach共振，包括13个弹性P波共振和6个宽大的D波共振，$^{41} $ k原子的不同自旋状态组合的田地组合最多600〜g。进行多通道量子缺陷理论计算以分配这些共振，结果在改善输入参数后与实验值显示出完美的一致性。观察到的宽P波和D波共振显示了完整的分辨率结构。它们可以作为非零部分波主导的物理学的重要模拟器。
We have observed 69 $^{41}$K-$^6$Li interspecies Feshbach resonances including 13 elastic p-wave resonances and 6 broad d-wave resonances of $^{41}$K atoms in different spin-state combinations at fields up to 600~G. Multi-channel quantum defect theory calculation is performed to assign these resonances and the results show perfect agreement with experimental values after improving input parameters. The observed broad p- and d- wave resonances display a full resolved multiplet structure. They may serve as important simulators to nonzero partial wave dominated physics.
