摘要：
在中性原子光学晶格钟中，高阶原子极化率项导致钟跃迁频移，该频移依赖于运动状态且与光学晶格深度呈非线性关系。我们提出利用辅助光学晶格来补偿E2-M1差分极化率的影响，或将相关系数调至有利值。我们表明，将此方法应用于Sr和Hg光学晶格钟时，由光学晶格引起的钟跃迁频率不确定度可低至甚至低于10^-19量级。最后，该方案易于实验实现，可在现有装置中实施和测试。
英文摘要：
In neutral atom optical clocks, the higher-order atomic polarizability terms lead to the clock transition frequency shift which is motion-state dependent and nonlinear with the optical lattice depth. We propose to use an auxiliary optical lattice to compensate the influence of the E2-M1 differential polarizability or tune the associated coefficient to a favorable value. We show that by applying this method to Sr and Hg optical lattice clocks, the low or even sub-10-19 clock transition frequency uncertainty from the optical lattice becomes feasible. Finally, the proposed scheme is simple for experimental realization and can be implemented and tested in the existing setups.
