Wichmann-Kroll Correction to the Interelectronic Interaction in He- and Li-Like Ions
J. Sommerfeldt, V. A. Yerokhin, Z. Harman +1
The paper calculates the higher‑order Wichmann‑Kroll QED correction to the interelectronic interaction in helium‑ and lithium‑like ions, improving numerical convergence and providi…

Two-loop electron self-energy for low nuclear charges
V. A. Yerokhin, Z. Harman, C. H. Keitel
Calculations of the two-loop electron self-energy for the Lamb shift are reported, performed to all orders in the nuclear binding strength parameter (where is the nu…

Improved bound-electron g-factor theory through complete two-loop QED calculations
Bastian Sikora, Vladimir A. Yerokhin, Christoph H. Keitel +1
The two-loop self-energy correction to the bound-electron -factor in hydrogenlike ions is investigated, taking into account the electron-nucleus interaction exactly. This all-or…
