Sturmian basis set for the Dirac equation with finite nuclear size: Application to polarizability, Zeeman and hyperfine splitting, and vacuum polarization
V. K. Ivanov, D. A. Glazov, A. V. Volotka
We investigate the application of the Sturmian basis set in relativistic atomic structure calculations. We propose a simple implementation of this approach and demonstrate its abil…

Vacuum polarization and Wichmann-Kroll correction in the finite basis set approximation
V. K. Ivanov, S. S. Baturin, D. A. Glazov +1
The finite basis set method is commonly used to calculate atomic spectra, including QED contributions such as bound-electron self-energy. Still, it remains problematic and underexp…
