Ultralight dark matter exhibits recoherence due to the solar gravitational potential, yielding formally divergent coherence times at long timescales and enhanced search sensitivity.
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.
Numerical study with realistic LISA orbits and Bayesian methods finds that scalar ULDM signals can be discriminated from quasi-monochromatic GW signals.
