Earth screening of quadratically coupled ultralight dark matter produces a multi-band frequency structure in the induced force whose sideband amplitudes vary annually, enabling improved constraints from MICROSCOPE and future EP missions.
A new parameter κ is defined to capture charge-dependent equivalence principle violations, with existing experiments constraining |κ| < 2.1 × 10^{-4} kg/C at 95% CL, eleven orders weaker than composition bounds.
Proposes satellite-based artificial pulsar polarization arrays (APPA) that simulations show can set tighter 95% C.L. upper limits on g_aγ than ground observations for axion masses 10^{-22} to 10^{-18} eV.
Derives the power spectrum evolution and cross-spectra for arbitrary multi-species wave and particle dark matter, incorporating free-streaming, Jeans scales, and intrinsic fluctuations.
Axion-like fields coupled to the Nieh-Yan term generate a chiral GW background during radiation domination, with parameter space explored for detectability in PTA and space-based observatories.
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.
Pre-exciting the target mode in a microwave cavity enables coherent first-order amplification of dark photon signals, yielding at least an order-of-magnitude sensitivity gain over vacuum-cavity methods despite shot noise.
In asymptotically safe gravity, dimension-five couplings of ultralight scalar dark matter to gauge field strengths vanish and are not generated perturbatively.
Derives suppression of adiabatic perturbations and scale-dependent growth of isocurvature power in warm wave dark matter, verifies with Schrödinger-Poisson simulations, and proposes an analytic halo mass function.
For Lμ-Lτ gauge forces with g ≳ 10^{-18}, Schwinger neutrino production in neutron stars alters composition, invalidates merger constraints at g ≳ 10^{-17}, and could yield detectable ~100 MeV neutrino fluxes from young stars at ~100 pc.
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.
Dark photon solitons emit photons through external-field dipole radiation and kinetic mixing, offering a novel astrophysical signature for wave-like dark matter.
Supersymmetry can stabilize an ultralight dilaton dark matter candidate, but gravity restricts its Standard Model couplings to undetectable levels, making consistent model building involved.
Systematic study of scalar and vector ULDM interactions on long-baseline neutrino oscillations finds order-of-magnitude weaker constraints for m_φ ≲ 10^{-17} eV due to stochastic effects, with combined T2K+NOvA data showing no alleviation of δ_CP discrepancy.
A review deriving couplings, noise spectra, SNRs, and quantum techniques like squeezing for detectors in dark matter, GW, and mechanical sensor experiments.
