We investigate Feshbach resonances in collisions of high-spin atoms such as Er and Dy with closed-shell atoms such as Sr and Yb, using coupled-channel scattering and bound-state calculations. We consider both low-anisotropy and high-anisotropy limits. In both regimes, we find many resonances with a wide variety of widths. The wider resonances are suitable for tuning interatomic interactions, while some of the narrower resonances are highly suitable for magnetoassociation to form high-spin molecules. These molecules might be transferred to short-range states, where they would have large magnetic moments and electric dipole moments that can be induced with very low electric fields. The results offer the opportunity to study mixed quantum gases where one species is dipolar and the other is not and open up important prospects for a new field of ultracold high-spin polar molecules.

由超冷原子形成高旋转极性分子的前景

我们使用耦合通道散射和束缚态计算研究了高自旋原子（例如Er和Dy）与闭壳原子（例如Sr和Yb）碰撞中的Feshbach共振。我们同时考虑了低各向异性和高各向异性极限。在这两种情况下，我们发现许多共振现象的宽度各不相同。较宽的共振适合调整原子间相互作用，而一些较窄的共振非常适合磁缔合以形成高自旋分子。这些分子可能会转移到短程状态，在短程状态下，它们将具有很大的磁矩和电偶极矩，这些磁矩和电偶极矩可以通过非常低的电场来感应。
