标题： Paschen-Back effect and Rydberg-state diamagnetism in vapor-cell electromagnetically induced transparency

摘要： 我们报告在0.7 T磁场下的铷原子蒸汽细胞里，涉及的所有能级都处于超精细帕申-巴克效应区域的里德伯态电磁诱导透明（EIT）现象，其中里德伯态与磁场表现出强烈的抗磁相互作用。 EIT光谱中同时存在 $^{85}\mathrm{Rb}$ 和 $^{87}\mathrm{Rb}$ 的信号。 这种同位素混合的Rb细胞特性使我们能够将磁场强度测量到 $\pm 0.12$% 的相对不确定度内。 测量得到的光谱与蒙特卡罗计算结果高度一致，并表明里德伯能级的去相位速率出乎意料地大。 模型中包含了由于磁场微小不均匀性引起的线形位移和展宽。 显示英文摘要

摘要： We report on rubidium vapor-cell Rydberg electromagnetically induced transparency (EIT) in a 0.7~T magnetic field where all involved levels are in the hyperfine Paschen-Back regime, and the Rydberg state exhibits a strong diamagnetic interaction with the magnetic field. Signals from both $^{85}\mathrm{Rb}$ and $^{87}\mathrm{Rb}$ are present in the EIT spectra. This feature of isotope-mixed Rb cells allows us to measure the field strength to within a $\pm 0.12$\% relative uncertainty. The measured spectra are in excellent agreement with the results of a Monte Carlo calculation and indicate unexpectedly large Rydberg-level dephasing rates. Line shifts and broadenings due to small inhomogeneities of the magnetic field are included in the model.
