Particle physics today faces the challenge of explaining the mystery of dark matter, the origin
of matter over anti-matter in the Universe, the origin of the neutrino masses, the apparent …

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 …

This work tabulates measured and derived values of coefficients for Lorentz and CPT
violation in the standard-model extension. Summary tables are extracted listing maximal …

Quantum electrodynamics (QED) is one of the most fundamental theories of physics and has
been shown to be in excellent agreement with experimental results,,,–. In particular …

In 1928, Dirac published an equation that combined quantum mechanics and special
relativity. Negative-energy solutions to this equation, rather than being unphysical as initially …

We review progress in the study of antinuclei, starting from Dirac's equation and the
discovery of the positron in cosmic-ray events. The development of proton accelerators led …

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 …

The spectrum of the hydrogen atom has played a central part in fundamental physics over
the past 200 years. Historical examples of its importance include the wavelength …

When Kai Zuber's pioneering text on neutrinos was published in 2003, the author correctly
predicted that the field would see tremendous growth in the immediate future. In that book …

We report on the precise measurement of the atomic mass of a single proton with a purpose-
built Penning-trap system. With a precision of 32 parts per trillion our result not only …
