摘要

我们展示了一种观测和分析单氟化钡（Ba138F19）X2Σ+,N=0 基态中所有超频级之间多级相干的自旋过程方法。该信号对状态准备的拉比频率以及在寻找永久电偶极矩（EDM）时施加的外部电场和磁场很敏感。在获得的干涉频谱中，电场和拉比频率与 EDM 可同时观测到。这种方法减少了系统偏差，也减少了此类精确测量的辅助测量次数。

Spin-precession method for sensitive electric dipole moment searches

We demonstrate a spin-precession method to observe and analyze multilevel coherence between all hyperfine levels in the

X^{2} Σ^{+}, N = 0

ground state of barium monofluoride (

{}^{138}{Ba} {}^{19}F

). The signal is sensitive to the state-preparation Rabi frequency and external electric and magnetic fields applied in searches for a permanent electric dipole moment (EDM). In the obtained interference spectrum, the electric field and Rabi frequency become observable simultaneously with the EDM. This method reduces systematic biases and the number of auxiliary measurements for such precision measurements.
