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 nuc…
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…
Nuclear magnetic shielding in heliumlike ions
Vladimir A. Yerokhin, Krzysztof Pachucki, Zoltán Harman +1
Ab initio QED calculations of the nuclear magnetic shielding constant in helium-like ions are presented. We combine the nonrelativistic QED approach based on an expansion in powers…
