论文摘要
We report on the direct optical production and spectroscopy of $^1\mathrm{S}_0\mbox{-}^3\mathrm{P}_0$ molecules with large binding energy using the clock transition of $^{171}\mathrm{Yb}$, and on the observation of the associated orbital Feshbach resonance near $ 1300 \，\ Mathrm {g} $。我们通过在深度光学晶格中的时钟线光谱法测量闭合通道二聚体和开放通道对状态能的磁场依赖性。此外，我们表明，可以通过选择晶格波长对陷阱深度的一阶不敏感。最后，我们确定了基本的内部和内膜间散射长度，并探测了相应对态的稳定性，在两个内膜间相互作用通道中找到了很长的寿命。这些结果对于分子时钟和制备强烈相互交互的多功能费米气体都是有希望的。
We report on the direct optical production and spectroscopy of $^1\mathrm{S}_0\mbox{-}^3\mathrm{P}_0$ molecules with large binding energy using the clock transition of $^{171}\mathrm{Yb}$, and on the observation of the associated orbital Feshbach resonance near $1300\,\mathrm{G}$. We measure the magnetic field dependence of the closed-channel dimer and of the open-channel pair state energy via clock-line spectroscopy in a deep optical lattice. In addition, we show that the free-to-bound transition into the dimer can be made first-order insensitive to the trap depth by choice of the lattice wavelength. Finally, we determine the fundamental intra- and interorbital scattering lengths and probe the stability of the corresponding pair states, finding long lifetimes in both interorbital interaction channels. These results are promising both for molecular clocks and for the preparation of strongly-interacting multiorbital Fermi gases.
