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 …

Experiments with cold and ultracold neutrons have reached a level of precision such that
problems far beyond the scale of the present standard model of particle physics become …

We report on a search for ultralow-mass axionlike dark matter by analyzing the ratio of the
spin-precession frequencies of stored ultracold neutrons and Hg 199 atoms for an axion …

The detection of variations of fundamental constants of the Standard Model would provide
us with compelling evidence of new physics, and could lift the veil on the nature of dark …

The theoretical description of fermions in the presence of Lorentz and CPT violation is
developed. We classify all Lorentz-and CPT-violating and invariant terms in the quadratic …

We report on the search for a CPT-and Lorentz-invariance-violating coupling of the He 3 and
Xe 129 nuclear spins (each largely determined by a valence neutron) to posited background …

The realization that Planck-scale physics can be tested with existing technology through the
search for spacetime-symmetry violation brought about the development of a …

We demonstrate an all-optical magnetometer capable of measuring the magnitude and
direction of a magnetic field using nonlinear magneto-optical rotation in cesium vapor …

In the past few decades, optical magnetometry has experienced remarkable development
and reached to an outstanding sensitivity. For magnetometry based on optical readout of …

We describe a magnetic gradiometer that operates at finite fields and uses an intense
pulsed laser to polarize a 87 Rb atomic ensemble and a compact vertical-cavity surface …
