The first critical tests of many-body and correlated Quantum Electro-Dynamics (QED) in medium-Z atomic systems

中Z原子系统中多体和关联量子电动力学（QED）的第一次临界测试。在计算原子中量子电动力学效应的高阶项和关联项时遇到了很大的困难。我们将首次测量对双电子QED非常敏感的中Z原子，并首次测试该区域的QED精确到1%。这种精确度将使我们对双电子系统、理论方法以及最近观察到的QED理论与实验之间的差异有新的认识。该建议遵循最近成功的实验工作，使用电子束离子阱（EBIT）的新功能。我们最近的出版物已经证明，这种新的方法可以产生新的见解光与物质的相互作用。

The first critical tests of many-body and correlated Quantum Electro-Dynamics (QED) in medium-Z atomic systems. Major difficulties are being encountered in the computation of high-order and correlated terms of Quantum Electro-Dynamical effects in atoms. We will make the first measurements for medium-Z atoms critically sensitive to two-electron QED, and the first tests of QED in this region accurate to 1%. This accuracy will allow new insight into two-electron systems, theoretical approaches, and recent observed discrepancies between QED theory and experiment. This proposal follows recent successful experimental work using new capabilities of Electron-Beam Ion Traps (EBITs). Our recent publications have proven that this novel approach can yield new insight into the interaction of light with matter.
