摘要
我们报告了首次在超冷 Yb 费米子的不同长寿命电子轨道间直接观测到快速自旋交换相干振荡。我们以模型无关的方式测量了驱动这一相干过程的交换相互作用强度。该观测使我们能够获取关于 Yb 原子轨道间碰撞性质的重要信息，并为两轨道量子磁性的典型模型的新型量子模拟铺平了道路。

备注
In this version of the preprint we have swapped the assignment of the eg+ and eg- states to the spectroscopic signals, thus correcting a wrong attribution in the previous version. As a consequence, the scattering lengths of the two states have been inverted. Hovewer, the main results of the paper remain unchanged. 5 pages (paper) + 3 pages (Supplemental Material)
