  • One-Electron Quantum Cyclotron as a Milli-eV Dark-Photon Detector. Physical review letters Fan, X., Gabrielse, G., Graham, P. W., Harnik, R., Myers, T. G., Ramani, H., Sukra, B. A., Wong, S. S., Xiao, Y. 2022; 129 (26): 261801

    Abstract

    We propose using trapped electrons as high-Q resonators for detecting meV dark photon dark matter. When the rest energy of the dark photon matches the energy splitting of the two lowest cyclotron levels, the first excited state of the electron cyclotron will be resonantly excited. A proof-of-principle measurement, carried out with one electron, demonstrates that the method is background free over a 7.4 day search. It sets a limit on dark photon dark matter at 148 GHz (0.6 meV) that is around 75 times better than previous constraints. Dark photon dark matter in the 0.1-1 meV mass range (20-200 GHz) could likely be detected at a similar sensitivity in an apparatus designed for dark photon detection.
