This work aims at a unified treatment of radiative corrections in neutral atoms, using both perturbative approaches (exploiting nonrelativistic QED) and a full nonperturbative treatment of the electron propagator. Studies will focus on the two loop Lamb shift, but will also address radiative binding corrections in cesium (relevant both for PNC and for hyperfine splitting) and energy calculations in helium and helium-like ions.

这项工作的目的是在一个统一的治疗中性原子的辐射校正，使用微扰的方法（利用非相对论QED）和一个完整的非微扰处理的电子传播。研究将集中在两个循环兰姆位移，但也将解决铯的辐射结合校正（相关的PNC和超精细分裂）和氦和类氦离子的能量计算。
