The last decade has seen unprecedented effort in dark matter model building at all mass
scales coupled with the design of numerous new detection strategies. Transformative …

The main mechanism responsible for Axion-Like-Particle (ALP) production in the early
universe is the so-called misalignment mechanism. Three regimes have been investigated …

Due to isolation from the environment with the protection of the full electronic shells, nuclear
spins of noble gas typically feature extraordinary long coherence times, high polarization …

Numerous observations suggest that there exist undiscovered beyond‐the‐standard‐model
particles and fields. Because of their unknown nature, these exotic particles and fields could …

Ultralight axionlike particles can contribute to the dark matter near the Sun, leading to a
distinct, stochastic signature in terrestrial experiments. We search for such particles through …

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

Numerous theories extending beyond the standard model of particle physics predict the
existence of bosons that could constitute dark matter. In the standard halo model of galactic …

Typical weak signal search experiments rely on resonant effects, where the resonance
frequency is scanned over a broad range, resulting in significant time consumption. In this …

High-intensity neutron beams, such as those available at the European Spallation Source
(ESS), provide new opportunities for fundamental discoveries. Here, we discuss a novel …

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 …
