Broadband and Resonant Approaches to Axion Dark Matter Detection
Broadband and Resonant Approaches to Axion Dark Matter Detection
When ultralight axion dark matter encounters a static magnetic field, it sources an effective electric current that follows the magnetic field lines and oscillates at the axion Compton frequency. We propose a new experiment to detect this axion effective current. In the presence of axion dark matter, a large toroidal …
