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…
Vacuum Polarization Effects in the Hyperfine Splitting of Hydrogen Like Ions
Junis Heiland Hoyo, Bastian Sikora
The hyperfine structure of bound electrons in hydrogen-like ions is considered with corrections to the energy levels due to vacuum polarization (VP). Corrections to the wave functi…
Precision spectroscopy on Be overcomes limitations from nuclear structure
Stefan Dickopf, Bastian Sikora, Annabelle Kaiser +7
Many powerful tests of the Standard Model of particle physics and searches for new physics with precision atomic spectroscopy are plagued by our lack of knowledge of nuclear proper…
