Description
Dark matter with masses much less than 1 eV/c² is treated as a classical field, commonly referred to as wavelike dark matter. Among the leading candidates is the axion, which may have a mass on the order of μeV and can be converted into ordinary microwave photons of minuscule amplitude under a strong magnetic field. Leading wavelike dark matter searches often employ SRF cavities as detectors for enhancing tiny signals. Therefore, the sensitivity of detection is proportion to the quality factor of the cavity.
Our research explores a broad range of cavity-based technologies for particle physics applications. For example, we aim to realize high-Q superconducting cavities at the single-photon regime at millikelvin temperatures to maximize sensitivity in dark matter detection. We also investigate the development of SRF cavities with high magnetic-field tolerance for axion searches. Additionally, we couple cavities to superconducting qubits to assess their potential for versatile quantum sensing technologies, such as single-photon counting or direct excitation of transmon qubits.
In this poster, we present our approach to dark matter detection using SRF cavities and report on the progress of each application.
