Quantum computers hold the promise of solving certain computational tasks much more
efficiently than classical computers. We review recent experimental advances towards a …

Like few other parameters, the mass of an atom, and its inherent connection with the atomic
and nuclear binding energy is a fundamental property, a unique fingerprint of the atomic …

Inner-shell electrons naturally sense the electric field close to the nucleus, which can reach
extreme values beyond 1015 V cm− 1 for the innermost electrons. Especially in few-electron …

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 …

Precise comparisons of the fundamental properties of matter–antimatter conjugates provide
sensitive tests of charge–parity–time (CPT) invariance, which is an important symmetry that …

This paper gives the 2002 self-consistent set of values of the basic constants and conversion
factors of physics and chemistry recommended by the Committee on Data for Science and …

Precise knowledge of the fundamental properties of the proton is essential for our
understanding of atomic structure as well as for precise tests of fundamental symmetries. We …

We present an experimental value for the g factor of the electron bound in hydrogenlike
oxygen, which is found to be gexpt= 2.000 047 025 4 (15)(44). The experiment was …

One of the fundamental properties of the proton is its magnetic moment, µ p. So far µ p has
been measured only indirectly, by analysing the spectrum of an atomic hydrogen maser in a …

The ALPHATRAP experiment at the Max-Planck Institute for Nuclear Physics in Heidelberg
aims at probing the validity of quantum electrodynamics in extremely strong electromagnetic …
