The standard model axion seesaw Higgs portal inflation (SMASH) model is a well-motivated,
self-contained description of particle physics that predicts axion dark matter particles to exist …

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 …

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

Novel interactions beyond the four known fundamental forces in nature (electromagnetic,
gravitational, strong and weak interactions), may arise due to" new physics" beyond the …

Axions are highly motivated hypothetical particles beyond the standard model that can be
dark matter candidates and address the strong CP problem. Here we search for axion …

Ultralight axion-like particles are well-motivated relics that might compose the cosmological
dark matter and source anomalous time-dependent magnetic fields. We report on terrestrial …

Searching for exotic interactions provides a path for exploring new particles beyond the
standard model. Here, we used an ensemble-NV-diamond magnetometer to search for an …

Precision measurements of anomalous spin-dependent interactions are often hindered by
magnetic noise and other magnetic systematic effects. Atomic comagnetometers use the …

In this paper, we demonstrate an all-optical spin-exchange relaxation-free atomic
magnetometer based on optical-fiber coupling, which simultaneously transmits orthogonally …

A bstract In the presence of axion dark matter, fermion spins experience an “axion wind”
torque and an “axioelectric” force. We investigate new experimental probes of these effects …
