In this talk, I will discuss a theoretical proposal for a new class ?of detectors for dark photon and axion dark matter at frequencies from the infrared through the ultraviolet based on dielectric haloscopes and high precision and efficiency single photon detectors, as well as some recent experimental progress.
A well-motivated class of dark matter candidates including axions and dark photons takes the form of coherent oscillations of a light bosonic field. If the dark matter couples to Standard Model states it may be possible to detect it via absorptions in a laboratory target. Current experiments of this kind include cavity-based resonators that convert bosonic dark matter to electromagnetic fields operating at microwave frequencies. In periodic photonic materials, bosonic dark matter can efficiently convert to detectable single photons. With feasible experimental techniques, these detectors can probe significant new parameter space for axion and ?dark photon dark matter in the 0.1-10 eV mass range.
