Bound-electron self-energy calculations in Feynman and Coulomb gauges: detailed analysis
M. A. Reiter, E. O. Lazarev, D. A. Glazov +2
The energy correction associated with the self-energy diagram is the leading (in magnitude) and fundamental (in significance) contribution to the Lamb shift in highly charged ions.…

Thermal one-loop self-energy correction for hydrogen-like systems: Relativistic approach
M. A. Reiter, D. A. Solovyev, A. A. Bobylev +2
Within a fully relativistic framework, the one-loop self-energy correction for a bound electron is derived and extended to incorporate the effects of external thermal radiation. In…

Applicability of the Dirac-Fock method combined with Core Polarization in calculations of alkali atoms
A. A. Bobylev, J. J. Lopez-Rodriguez, P. A. Kvasov +3
In this work, we investigate the applicability of the core-polarization-corrected Dirac--Fock method, formulated within the framework of the local Dirac--Hartree--Fock (LDF) potent…
