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 electric dipole moment of the neutron and an axion-wind spin-precession effect. No signal consistent with dark matter is observed for the axion mass range 1024 eV ma 10 17 eV. Our null result sets the first laboratory constraints on the coupling of axion dark matter to gluons, which improve on astrophysical limits by up to 3 orders of magnitude, and also improves on previous laboratory constraints on the axion coupling to nucleons by up to a factor of 40.

Search for New Physics with Atoms and Molecules (2017, methodology): “Abel et al. (2017) used the CASPEr wind approach to analyze data from a search for the neutron EDM to constrain ALP DM with 10−24 ≲mac2 ≲ 10−17 eV. In the KSVZ family of QCD axion models (Kim, 1979; Shifman, Vainshtein, and Zakharov, 1980), the coupling of the axion to electron spins is nominally ze”
New experimental approaches in the search for axion-like particles (2018, background): “Interestingly, the results of these experiments can also analysed to constrain the oscillating hypothesis [402].”
Revealing the dark matter halo with axion direct detection (2017, methodology): “In addition to the long-running ADMX experiment [2–4], there has been a raft of new ideas for directly detecting axion DM, including ABRACADABRA [5], CASPEr [6], CULTASK [7], DM Radio [8,9], MADMAX [10–13], HAYSTAC [14–16], nEDM [17,18], ORGAN [19], QUAX [20–22], TASTE [23], and more [24–46].”
