Effects of QED and Beyond from the Atomic Binding Energy

Soff, G.; Bedniakov, I.; Beier, T.; Erler, F.; Goidenko, I. A.; Jentschura, U. D.; Labzowski, L. N.; Nefiodov, A. V.; Plunien, G.; Schützhold, R.; Zschocke, S.

Atomic binding energies are calculated at utmost precision. A report on the current status of
Lamb-shift predictions for hydrogenlike ions, including all quantum electrodynamical corrections to first
and second order in the fine structure constant alpha is presented. All relevant nuclear effects are
taken into account. High-precision calculations for the Lamb shift in hydrogen are presented. The
hyperfine structure splitting and the g factor of a bound electron in the strong electromagnetic field of a
heavy nucleus is considered. Special emphasis is also put on parity violation effects in atomic systems.
For all systems possible investigations beyond precision tests of quantum electrodynamics are
considered.
