Higher-order corrections to the field shift in atomic systems
V. A. Yerokhin, Z. Harman, C. H. Keitel
The paper develops a systematic expansion for higher-order contributions to the field shift in atomic spectra, validates it with numerical calculations for hydrogen-like ions, and…
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…
Atomic parity violation in highly charged Ca and Pb ions
A. V. Viatkina, Ch. G. Mertens, B. Ohayon +2
We calculate parity-violation-induced E1 amplitudes for the and transitions in H- and Li-like ions of Ca, Ca, and $^{2…
Two-body -state energies at order
VojtÄch Patkóš, Vladimir A. Yerokhin, Krzysztof Pachucki
We present an analytical calculation of the complete correction to energies of -levels of two-body systems consisting of the spin- or extended-size particles wi…
Model-independent determination of nuclear charge radii from Li-like ions
V. A. Yerokhin, B. Ohayon
We demonstrate that recent advances in QED theory of Li-like ions [V. A. Yerokhin et al., Phys. Rev. A 112, 042801 (2025)] enable determinations of absolute nuclear charge radii fo…
QED nuclear recoil effect in helium isotope shift
Krzysztof Pachucki, VojtÄch Patkóš, Vladimir A. Yerokhin
We present a detailed investigation of the leading-order QED correction with inclusion of the finite-nuclear-mass effects. Previously, this correction had been calculated w…
