The Any Light Particle Search II (ALPS II) is a light-shining-through-a-wall (LSW) experiment located at DESY in Hamburg, Germany, that is searching for axions and axion-like particles in the mass range below 0.1 meV. LSW experiments take advantage of the potential interaction between axions and two photons by shining a laser through a region of high magnetic field. This creates an axion field...
Dark photon dark matter (DP-DM) is one of the dark matter candidates. The DP-DM is theoretically predicted to have a weak coupling χ to ordinary photons. This results in the emission of the conversion photon at the electromagnetic boundary such as a metal surface when the DP-DM passes through.
The DOSUE-RR (Dark-photon dark-matter Observing System for Un-Explored Radio-Range) is a series of...
WISP Searches on a Fiber Interferometer (WISPFI) is a novel tabletop experiment using interferometric techniques applied to photonic crystal fibers searching for a resonant photon-axion conversion. It is independent of the local dark matter density which can highly reduce the sensitivity of axion experiments and could as well be the reason behind the null results of dark matter searches so...
