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 new terrestrial bounds on the coupling of axion-like particles to neutrons and protons. The detector uses nuclei of noble-gas and alkali-metal atoms and operates in the Spin-Exchange Relaxation-Free (SERF) regime, achieving high sensitivity to axion-like dark matter fields. Conducting a month-long search, we cover the mass…

New constraints on axion-like dark matter using a Floquet quantum detector

Dark matter is one of the greatest mysteries in physics. It interacts via gravity and composes most of our universe, but its elementary composition is unknown. We search for nongravitational

Laboratory Constraints on the Neutron-Spin Coupling of feV-scale Axions

Ultralight axion-like 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 their

Axion-like relics: new constraints from old comagnetometer data

The noble-alkali comagnetometer, developed in recent years, has been shown to be a very accurate measuring device of anomalous magnetic-like fields. An ultra-light relic axion-like particle can

Search for Axionlike Dark Matter through Nuclear Spin Precession in Electric and Magnetic Fields

We report on a search for ultra-low-mass axion-like dark matter by analysing the ratio of the spinprecession frequencies of stored ultracold neutrons and 199Hg atoms for an axion-induced oscillating

The cosmic axion spin precession experiment (CASPEr): a dark-matter search with nuclear magnetic resonance

The cosmic axion spin precession experiment (CASPEr) is a nuclear magnetic resonance experiment (NMR) seeking to detect axion and axion-like particles which could make up the dark matter present in

Limits on Axions and Axionlike Particles within the Axion Window Using a Spin-Based Amplifier.

Searches for the axion and axionlike particles may hold the key to unlocking some of the deepest puzzles about our Universe, such as dark matter and dark energy. Here, we use the recently

Search for Axionlike Dark Matter with a Liquid-State Nuclear Spin Comagnetometer.

The result constrains the coupling of nuclear spins to the gradient of the square of the axionlike dark matter field, improving over astrophysical limits by orders of magnitude over the entire range of particle masses probed.

Spin Precession Experiments for Light Axionic Dark Matter

Axion-like particles are promising candidates to make up the dark matter of the universe, but it is challenging to design experiments that can detect them over their entire allowed mass range. Dark

Searching for Earth/Solar axion halos

We discuss the sensitivity of the present and near-future axion dark matter experiments to a halo of axions or axion-like particles gravitationally bound to the Earth or the Sun. Such halos, assuming

Constraints on bosonic dark matter from ultralow-field nuclear magnetic resonance

The cosmic axion spin precession experiment (CASPEr), an NMR-based dark-matter search, uses ultralow-field NMR to probe the axion-fermion “wind” coupling and dark-photon couplings to nuclear spins, establishing new experimental bounds for dark matter bosons with masses ranging from 1.8 × 10−16 to 7.8×10−14 eV.
