We introduce a mechanism by which a misaligned ALP can be dynamically converted into a dark photon in the presence of a background magnetic field. An abundance of non-relativistic ALPs will produce dark photons with momentum of order the inhomogeneities in the background field; therefore a highly homogeneous field will produce non-relativistic dark photons. In the large magnetic field regime,...
Kinetically mixed dark photons and axionlike particles are both viable ultralight candidates for dark matter. These candidates can source an oscillating magnetic field signal inside an experimental apparatus. Existing experiments search for this signal by taking advantage of resonant enhancements, e.g. from a lumped-element circuit or resonant cavity, but such techniques become difficult for...
Studying the early universe provides possible answers to many open questions such as the origin and composition of dark matter. Primordial black holes (PBHs) are a compelling channel to probe and understand the cosmic history of dark matter. Light PBHs, which have Hawking evaporate before BBN, can produce both Standard Model particles and dark matter via gravitational production. In this talk...
