Reexamining Black-Body Shifts for Hydrogenlike Ions
U. D. Jentschura, M. Haas
We investigate black-body induced energy shifts for low-lying levels of atomic systems, with a special emphasis on transitions used in current and planned high-precision experiment…

Two-Loop Effects and Current Status of the 4He+ Lamb Shift
Ulrich D. Jentschura, Martin Haas
We report on recent progress in the treatment of two-loop binding corrections to the Lamb shift, with a special emphasis on S and P states. We use these and other results in order…

Comparison of classical and second quantized description of the dynamic Stark shift
M. Haas, U. D. Jentschura, C. H. Keitel
We compare the derivation of the dynamic Stark shift of hydrogenic energy levels in a classical framework with an adiabatically damped laser-atom interaction, which is equivalent t…
