Nonrelativistic QED approach to the bound-electron g factor
K. Pachucki, U. D. Jentschura, V. A. Yerokhin
Within a systematic approach based on nonrelativistic quantum electrodynamics (NRQED), we derive the one-loop self-energy correction of order alpha (Zalpha)^4 to the bound-electron…

Two-Loop Bethe Logarithms for Higher Excited S Levels
Ulrich D. Jentschura
Processes mediated by two virtual low-energy photons contribute quite significantly to the energy of hydrogenic S states. The corresponding level shift is of the order of (alpha/pi…
