摘要:

我们展示了一种自旋进动方法来观察和分析所有的超精细水平之间的多层次的相干性在$X ^2Σ^+,N=0$基态的一氟化钡($^{138}$ Ba $^{19}$ F)。该信号是敏感的状态准备拉比频率和外部电场和磁场施加在搜索一个永久的电偶极矩(EDM)。在所获得的干涉频谱中,电场和拉比频率变得与电火花加工同时可观察。该方法减少了系统偏差和用于这种精确测量的辅助测量的数量。

英文摘要:

We demonstrate a spin-precession method to observe and analyze multi-level coherence between all hyperfine levels in the $X ^2Σ^+,N=0$ 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.
