A dc SQUID operated at the flux sweet spot with lock-in modulation yields an ultra-broadband axion search with projected sensitivity |g_aγγ| ≳ 10^{-16} GeV^{-1} across 15 orders of magnitude in mass.

abstract
We show that cold dark matter axions thermalize and form a Bose-Einstein condensate. We obtain the axion state in a homogeneous and isotropic universe, and derive the equations governing small axion perturbations. Because they form a BEC, axions differ from ordinary cold dark matter in the non-linear regime of structure formation and upon entering the horizon. Axion BEC provides a mechanism for the production of net overall rotation in dark matter halos, and for the alignment of cosmic microwave anisotropy multipoles.
