This article reviews recent developments in tests of fundamental physics using atoms and
molecules, including the subjects of parity violation, searches for permanent electric dipole …

Recent developments in frequency metrology and optical clocks have been based on
electronic transitions in atoms and singly charged ions as references. The control over all …

Optical atomic clocks are the most accurate measurement devices ever constructed and
have found many applications in fundamental science and technology,–. The use of highly …

Electrons bound in highly charged heavy ions such as hydrogen-like bismuth 209Bi82+
experience electromagnetic fields that are a million times stronger than in light atoms …

We have measured the ground-state g factor of boronlike argon Ar 40 13+ with a fractional
uncertainty of 1.4× 10-9 with a single ion in the newly developed Alphatrap double Penning …

We report on the successful demonstration of a novel scheme for detecting optical
transitions in highly charged ions. We applied it to determine the frequency of the dipole …

A method is proposed to determine the M 1 nuclear transition amplitude and hence the
lifetime of the “nuclear clock transition” between the low-lying (∼ 8 eV) first isomeric state …

Recent progress in quantum electrodynamics (QED) calculations of highly charged ions is
reviewed. The theoretical predictions for the binding energies, the hyperfine splittings, and …

A rigorous QED evaluation of the two-photon exchange corrections to the g factor of
lithiumlike ions is presented. The screened self-energy corrections are calculated for the …

The paper presents the current status of the theory of bound-electron g factor in highly
charged ions. The calculations of the relativistic, quantum electrodynamics (QED), nuclear …
