abstract
Axion-gluon interaction induces quadratic couplings between the axion and the matter fields. We find that, if the axion is an ultralight dark matter field, it induces small oscillations of the mass of the hadrons as well as other nuclear quantities. As a result, atomic energy levels oscillate. We use currently available atomic spectroscopy data to constrain such axion-gluon coupling. We also project the sensitivities of future experiments, such as ones using molecular and nuclear clock transitions. We show that current and near-future experiments constrain a finely-tuned parameter space of axion models. These can compete with or dominate the already-existing constraints from oscillating neutron electric dipole moment and supernova bound, in addition to those expected from near future magnetometer-based experiments. We also briefly discuss the reach of accelerometers and interferometers.

Collective nucleon scattering in neutron-star matter suppresses the effective absorption of ultralight bosons at the long wavelengths relevant for superradiance, weakening the link between stellar cooling bounds and superradiant instability rates.
In asymptotically safe gravity, dimension-five couplings of ultralight scalar dark matter to gauge field strengths vanish and are not generated perturbatively.
White dwarf mass-radius data exclude large parameter space for ultralight scalars quadratically coupled to fermions by predicting forbidden radius gaps and mass shifts toward the Chandrasekhar limit or altered maximum masses.
Ultralight dark matter induces oscillating CKM elements that can be probed at NA62 through direct counting of meson decay events, which avoids sensitivity loss from unknown particle flux.
Monitor and Beacon TDI combinations reach g_aγ ~ 10^{-13} GeV^{-1} at high frequencies while Sagnac performs better at low frequencies, with ASTROD-GW probing axion-like dark matter masses down to 10^{-20} eV.
Numerical study with realistic LISA orbits and Bayesian methods finds that scalar ULDM signals can be discriminated from quasi-monochromatic GW signals.
