论文摘要
我们介绍了一种种间的研究Feshbach在Ultracold $^{7} $ li-$^{133} $ CS Bose-Bose-Bose混合物中的共鸣。我们在三种不同的自旋状态组合中找到十个种间共振。通过与耦合通道计算进行比较，我们将六个共振分配给$ s $波频道，其余的谐振为$ p $ - 波频道。我们使用$ S $ - 波的共振来完善耦合通道计算中LIC的基态电势，然后获得混合物的散射和结合状态的准确表征。我们的结果对于使用Ultracold $^{7} $ li-$^{133} $ CS混合物的将来实验将很有用。
We present a study of interspecies Feshbach resonances in ultracold $^{7}$Li-$^{133}$Cs Bose-Bose mixtures. We locate ten interspecies resonances in three different spin-state combinations. By comparing to coupled-channel calculations, we assign six of the resonances to $s$-wave channels and the rest to $p$-wave channels. We use the $s$-wave resonances to refine the ground-state potentials of LiCs in the coupled-channel calculations and then obtain an accurate characterization of the scattering and bound-state properties of the mixtures. Our results will be useful for future experiments with ultracold $^{7}$Li-$^{133}$Cs mixtures.
