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.

Suppressed Quantum Effects of Weakly Coupled Waves
Nonclassical (quantum) signatures of weakly coupled waves are suppressed by an extra power of the tiny conversion efficiency η (~10^-21 for axions, ~10^-33 for gravitons), so experiments cannot establish the quantizat...

Dark matter pair absorption
Pair absorption of two dark matter particles in atomic transitions can probe electroweak-scale couplings of mu-eV-to-eV mass bosonic dark matter, and could bound the cosmic neutrino background overdensity near 10^9.

Probing Quadratically Coupled Ultralight Dark Matter with the Laser Interferometer Space Antenna
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.

Ultralight Dark Matter from the Edge of Field Space
A scalar with hard field-space boundaries — a 'wallion' — is a viable ultralight dark-matter candidate whose exponentially small, radiatively stable mass and saturated relic density at large misalignment also suppress...

Probing Quadratically Coupled Ultralight Dark Matter with Pulsar Timing Arrays
For quadratically coupled ultralight dark matter, pulsar timing arrays can set competitive coherent-signal limits at 10^-24–10^-22 eV, while stochastic-signal limits remain weaker than equivalence-principle constraint...

Enhanced Axion-wind near Earth's Surface
A quadratically coupled ultralight scalar field develops a spatial profile around Earth that can boost the field-gradient 'axion wind' by orders of magnitude at low masses, and a nonzero incoming velocity removes the ...

Searching for coupled, hyperlight scalars across cosmic history
Hyperlight quadratically coupled scalars making up a few percent of dark matter are bounded to near- or sub-gravitational couplings to electrons and photons over 10^-31 to 10^-28 eV, with quasar spectra setting the st...

Ponderomotive Effects of Ultralight Dark Matter
Second-order shifts of electron mass and spin-precession frequencies from oscillating ultralight dark matter exist only for DM masses above the experimental frequency scale, making g-2 constraints much weaker than pre...

Thermo-Coupled Early Dark Energy
A scalar quadratically coupled to neutrinos can generate early dark energy-like dynamics whose energy density redshifts away faster than radiation, potentially easing the Hubble tension.
