论文摘要
Wannier-Start的光学晶格时钟已经证明了光学原子时钟的前所未有的测量精度。我们提出了对晶格灯光转移的系统评估,这是将该系统确立为准确的原子钟的必要下一步。通过精确控制晶格中的原子运动状态,我们报告了多极和超极贡献的准确测量以及操作晶格光移动,分数不确定性为3.5 $ \ times $ 10 $ {}^{ - 19} $。
A Wannier-Stark optical lattice clock has demonstrated unprecedented measurement precision for optical atomic clocks. We present a systematic evaluation of the lattice light shift, a necessary next step for establishing this system as an accurate atomic clock. With precise control of the atomic motional states in the lattice, we report accurate measurements of the multipolar and the hyperpolar contributions and the operational lattice light shift with a fractional frequency uncertainty of 3.5$\times$10${}^{-19}$.
