Quantum electrodynamics (QED) is the first successful and still the most successful quantum
field theory. Simple atoms, being essentially QED systems, allow highly accurate theoretical …

1.1. Background This article reports work carried out under the auspices of the Committee
on Data for Science and Technology (CODATA) Task Group on Fundamental Constants. 1 It …

1.1. Background This paper gives the complete 2006 CODATA self-consistent set of
recommended values of the fundamental physical constants and describes in detail the …

This review discusses progress in the new field of coherent matter waves, particularly with
respect to Bose–Einstein condensates. We give a short introduction to Bose–Einstein …

For more than 50years, Charlotte Moore's compilation of atomic energy levels and its
subsequent revisions have been the standard source of reference data for the spectra of …

The 2 S 1/2 hyperfine interval in atomic hydrogen was measured using Ramsey
spectroscopy with a thermal beam cooled to cryogenic temperatures. The measured value is …

We give a pedagogical description of the method to extract the charge radii and Rydberg
constant from laser spectroscopy in regular hydrogen (H) and deuterium (D) atoms, that is …

For more than 100 years, optical atomic/molecular frequency references have played
important roles in science and technology, and provide standards enabling precision …

The theory of the long-range interaction of metastable excited atomic states with ground-
state atoms is analyzed. We show that the long-range interaction is essentially modified …
