Description
The axion is particularly well motivated candidate for the dark matter comprising most of the mass of our visible Universe, leading to worldwide experimental and observational efforts towards its discovery. A primary technique in this search is the cavity haloscope, which is used to enhance the rate that dark matter axions convert to photons in a background electromagnetic field. As we discuss, the same haloscope technique can also be used to enhance the rate at which axions decay to two photons, as a manifestation of the Purcell effect. We explore this possibility, and show that it offers a novel method to explore the axion parameter space that is competitive and complimentary to other approaches
