abstract
We discuss models of ultralight scalar Dark Matter (DM) with linear and quadratic couplings to the Standard Model (SM). In addition to studying the phenomenology of linear and quadratic interactions separately, we examine their interplay. We review the different experiments that can probe such interactions and present the current and expected future bounds on the parameter space. In particular, we discuss the scalar field solution presented in [A. Hees, O. Minazzoli, E. Savalle, Y. V. Stadnik and P. Wolf, Phys.Rev.D 98 (2018) 6, 064051], and extend it to theories that capture both the linear and the quadratic couplings of the DM field to the SM. Furthermore, we discuss the theoretical aspects and the corresponding challenges for natural models in which the quadratic interactions are of phenomenological importance.

Ultralight dark matter exhibits recoherence due to the solar gravitational potential, yielding formally divergent coherence times at long timescales and enhanced search sensitivity.
LISA forecasts for quadratically coupled ultralight dark matter show competitive or superior sensitivity to terrestrial and astrophysical probes in selected mass windows, free of screening.
Introduces a directional force template for quadratic ultralight DM couplings, recasts MICROSCOPE constraints, and estimates sensitivity improvement in the anisotropic regime.
Nested cylinders in MICROSCOPE act as a dark-matter-wave interferometer, producing rotation-modulated signals that yield leading constraints on quadratic DM-nucleon couplings for masses 10^{-3}--10^{-2} eV.
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.
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.
Nelson-Barr mechanism yields ultralight scalar dark matter inducing time-periodic variation in CKM matrix elements, distinguishable from QCD axion and detectable via nuclear clocks.
The paper formulates dark matter detection in matter-wave interferometers as an open-system problem using Schwinger-Keldysh effective field theory, revealing channel asymmetries and Bose/Pauli factors for elastic scattering.
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.
Incorporating timing information from time-dependent new physics signals can improve LHC search sensitivity by up to a factor of two compared to standard time-invariant analyses.
Self-interaction bounds from cosmology constrain ultralight dark matter couplings to neutrinos, electrons, and light quarks via unavoidable quantum loop corrections.
