Résumé |
I will discuss an approach to search for axion dark matter with an especially desigend superconducting radio
frequency cavity. Our approach exploits axion-induced transitions between nearly degenerate resonant
modes of frequency close to a GHz. Compared to traditional detection strategies this allows for
parametrically enhanced signal power for axions lighter than a GHz (~micro-eV). The projected sensitivity
covers unexplored parameter space for QCD axion dark matter for axion masses between a GHz and 10 MHz.
It is also sensitive to about eight orders of magnitude in axion-like dark matter coupling to photons for axion
masses between GHz and Hz. |
