Title: Heterodyne Detection of Axion Dark Matter with Superconducting Cavities
Abstract: Detecting ultralight axion dark matter is a major goal of next generation direct detection experiments. I will discuss ongoing theoretical and experimental developments aimed at detecting axions with mass well below the micro-eV scale, corresponding to Compton wavelengths much larger than the typical size of tabletop experiments. The approach relies on axion-induced transitions between two nearly degenerate resonant modes of a single superconducting radio-frequency cavity. Compared to conventional searches employing static magnetic fields, this approach parametrically enhances signal power at low axion masses, opening up sensitivity to previously unexplored regions of parameter space.
