论文摘要
我们报告了$^{171} \ mathrm {yb} $原子的旋转 - 交换动力学的观察，处于基础状态$^1 \ mathrm {s} _0 $，以及在静态状态$^3 \ 3 \ mathrm {p} _0 $中。我们使用近谐振和魔术波长的光学晶格实现了混合维度的两轨系统，其中$^1 \ mathrm {s} _0 $和$^3 \ 3 \ Mathrm {p} _0 $原子在一维管中是沿三维管局局部的三个维度。通过利用光学船尾grach方法，我们观察到由$^1 \ mathrm {s} _0 $原子的旋转去极化，这是由与$^3 \ Mathrm {p} _0 $ Atom诱导的旋转交流相互作用所引起的。我们的工作可以为近代效应的量子模拟开辟道路。
We report on the observation of the spin-exchange dynamics of $^{171}\mathrm{Yb}$ atoms in the ground state $^1\mathrm{S}_0$ and in the metastable state $^3\mathrm{P}_0$. We implement the mixed-dimensional two-orbital system using a near-resonant and magic-wavelength optical lattices, where the $^1\mathrm{S}_0$ and $^3\mathrm{P}_0$ atoms are itinerant in a one-dimensional tube and localized in three dimensions, respectively. By exploiting an optical Stern-Gerlach method, we observe the spin depolarization of the $^1\mathrm{S}_0$ atoms induced by the spin-exchange interaction with the $^3\mathrm{P}_0$ atom. Our work could open the way to the quantum simulation of the Kondo effect.
