论文摘要
我们通过实验研究了由电场引起的Rydberg水平移位，该电场由Rydberg Atom碰撞引起的原子集合中的电离产生。通过控制地下原子密度和光激发过程，通过Rydberg原子之间的碰撞引起的电荷颗粒的密度改变了。我们使用Rydberg电磁诱导的透明度（EIT）光谱测量了Rydberg水平的移位，并使用半经典模型来解释了物理起源。实验结果与数值模拟非常吻合。这些能量转移对于通过使用Rydberg EIT的微波场的自我校准感测非常重要。此外，与共振激发案例相反，具有高信噪比的狭窄线宽光谱对于高精度测量值将有用。
We experimentally studied the Rydberg level shift caused by the electric field, which is generated by Rydberg atom collision induced ionization in a cesium atomic ensemble. The density of charged particles caused by collisions between Rydberg atoms is changed by controlling the ground-state atomic density and optical excitation process. We measured the Rydberg level shift using Rydberg electromagnetically-induced-transparency (EIT) spectroscopy, and interpreted the physical origin using a semi-classical model. The experimental results are in good agreement with the numerical simulation. These energy shifts are important for the self-calibrated sensing of microwave field by the employing of Rydberg EIT. Moreover, in contrast to the resonant excitation case, narrow-linewidth spectroscopy with high signal-to-noise ratio would be useful for high-precision measurements.
