标题： Nonlinear Zeeman effect, line shapes and optical pumping in electromagnetically induced transparency

摘要： 我们在室温铯蒸气细胞中对一种里德伯电磁诱导透明（EIT）系统进行塞曼光谱分析，在高达50高斯的磁场和多种偏振配置下进行。 形成阶梯型EIT系统的$\vert 6S_{1/2}, F_g=4 \rangle$基态、$\vert 6P_{3/2}, F_e=5 \rangle$中间态和$\vert 33S_{1/2} \rangle$里德伯态的磁相互作用分别处于线性塞曼、二次塞曼和深超精细帕申-巴克效应区域。 在约5高斯的磁场开始，光谱出现不对称性，在磁场$\gtrsim40$高斯时变得尤为显著。 我们使用量子蒙特卡洛波函数方法对光谱进行定量建模。 模拟光谱与实验数据有良好一致性。 光谱中的不对称性部分是由于二次塞曼效应引起的能级位移，但也反映了磁场中光学抽运与EIT之间的复杂相互作用。 讨论了其在测量应用中的相关性。 %模拟还用于研究磁场中的光学抽运，并探讨光学抽运与EIT之间的相互作用，这会减少光子散射和光学抽运。 显示英文摘要

摘要： We perform Zeeman spectroscopy on a Rydberg electromagnetically induced transparency (EIT) system in a room-temperature Cs vapor cell, in magnetic fields up to 50~Gauss and for several polarization configurations. The magnetic interactions of the $\vert 6S_{1/2}, F_g=4 \rangle$ ground, $\vert 6P_{3/2}, F_e=5 \rangle$ intermediate, and $\vert 33S_{1/2} \rangle$ Rydberg states that form the ladder-type EIT system are in the linear Zeeman, quadratic Zeeman, and the deep hyperfine Paschen-Back regimes, respectively. Starting in magnetic fields of about 5~Gauss, the spectra develop an asymmetry that becomes paramount in fields $\gtrsim40$~Gauss. We use a quantum Monte Carlo wave-function approach to quantitatively model the spectra. Simulated spectra are in good agreement with experimental data. The asymmetry in the spectra is, in part, due to level shifts caused by the quadratic Zeeman effect, but it also reflects the complicated interplay between optical pumping and EIT in the magnetic field. Relevance to measurement applications is discussed. %The simulations are also used to study optical pumping in the magnetic field and to investigate the interplay between optical pumping and EIT, which reduces photon scattering and optical pumping.
