论文摘要
对少数电子，高$ z $离子的精确研究是用于探测高野外量子量子电动力学（BSQED）的特权领域。但是，此类测试的准确性受到核不确定的困扰，核不确定性通常大于所研究的BSQED效应。我们提出了一种与外来原子的替代方法，并表明在圆形的rydberg状态之间可以发现核贡献消失而BSQED效应仍然很大的过渡。当用新可用的量子传感探测器进行探测时，这些系统的灵敏度具有\ numrange {1} {2} {2}数量级的增长，而这些系统中的平均电场在很大程度上超过了schwinger限制。
Precision study of few-electron, high-$Z$ ions is a privileged field for probing high-field, bound-state quantum electrodynamics (BSQED). However, the accuracy of such tests is plagued by nuclear uncertainties, which are often larger than the BSQED effects under investigation. We propose an alternative method with exotic atoms, and show that transitions may be found between circular Rydberg states where nuclear contributions are vanishing while BSQED effects remain large. When probed with newly available quantum sensing detectors, these systems offer gains in sensitivity of \numrange{1}{2} orders of magnitude, while the mean electric field in these systems largely exceeds the Schwinger limit.
