利用里德堡态对锶的钟形相变的二次斯塔克位移进行了电测量。通过使用电磁感应透明测量高激发态的斯塔克位移，我们以足够的精度表征了电场，以提供对系统向时钟跃迁的严格约束。利用理论推导和实验验证的Rydberg态的极化率，我们可以测量不确定度远小于1的剩余场。这一分辨率允许我们将时钟跃迁的二次斯塔克移位的分数频率不确定度限制为。
Electrometry is performed using Rydberg states to evaluate the quadratic Stark shift of theclock transition in strontium. By measuring the Stark shift of the highly excitedstate using electromagnetically induced transparency, we characterize the electric field with sufficient precision to provide tight constraints on the systematic shift to the clock transition. Using the theoretically derived, and experimentally verified, polarizability for this Rydberg state, we can measure the residual field with an uncertainty well below 1. This resolution allows us to constrain the fractional frequency uncertainty of the quadratic Stark shift of the clock transition to.
