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 …

Recent years have seen the emergence of a new generation of collision and cold-chemistry
experiments in which cold atoms and ions are brought into contact in a controlled way in …

We search for ultralight scalar dark matter candidates that induce oscillations of the fine
structure constant, the electron and quark masses, and the quantum chromodynamics …

Precision measurements in molecules have advanced rapidly in recent years through
developments in techniques to cool, trap, and control. The complexity of molecules makes …

The applications of spin-based quantum sensors to measurements probing fundamental
physics are surveyed. Experimental methods and technologies developed for spin-based …

Efficient cooling of trapped charged particles is essential to many fundamental physics
experiments,, to high-precision metrology, and to quantum technology,. Until now …

We consider axions coupled to nucleons and photons only through the nucleon electric-
dipole moment (EDM) portal. This coupling is a model-independent feature of QCD axions …

Based on the notion that the local dark-matter field of axions or axionlike particles (ALPs) in
our Galaxy induces oscillating couplings to the spins of nucleons and nuclei (via the electric …

Möbius-ring resonators stem from a well-studied and fascinating geometrical structure which
features a one-sided topology, the Möbius strip, and have been shown to exhibit fermion …

We demonstrate that ultralight axion dark matter with a coupling to photons induces an
oscillating global terrestrial magnetic-field signal in the presence of the background …
