Vacuum polarization correction to atomic energy levels in the path integral formalism
Sreya Banerjee, Zoltán Harman
Vacuum polarization corrections to the energy levels of bound electrons are calculated using a perturbative path integral formalism. We apply quantum electrodynamics in a framework…
Stringent test of QED with hydrogenlike tin
J. Morgner, B. Tu, C. M. König +11
Inner-shell electrons naturally sense the electric field close to the nucleus, which can reach extreme values beyond for the innermost electrons. Espe…
Ultrastable optical, XUV and soft-x-ray clock transitions in open-shell highly charged ions
Chunhai Lyu, Christoph H. Keitel, Zoltán Harman
Highly charged ions (HCIs) are insensitive to external perturbations and are attractive for the development of ultrastable clocks. However, only a few HCI candidates are known to p…
Hadronic vacuum polarization correction to the bound-electron factor
Eugen Dizer, Zoltán Harman
The hadronic vacuum polarization correction to the factor of a bound electron is investigated theoretically. An effective hadronic Uehling potential obtained from measured cros…
