Incorporating sidereal modulation spectral features improves excess-power constraints on ultra-light dark matter by up to 36 percent at low frequencies, and an optimized cross-correlation statistic in the Band-Sampled-Data framework boosts sensitivity by up to 42 percent at low frequencies and 35 pe
Existence of an infinite class of spherically-symmetric solutions to the multi-field Schrödinger-Poisson system is established via global minimization of the energy functional on rotationally invariant H1 functions with fixed L2 norms per component, with the minima shown to be orbitally stable.
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.
Dark photon solitons emit photons through external-field dipole radiation and kinetic mixing, offering a novel astrophysical signature for wave-like dark matter.
