Title:
Ultralight Dark Matter Detection with Trapped Electrons
Speaker:
Abstract:
We have proposed and experimentally demonstrated a new way to search for ultralight dark matter using trapped electrons. The trapped electron serves as a high-Q resonator to search for dark photon and axion dark matter in the ~10-100 GHz mass range. We carried out a proof-of-principle experiment which achieved a limit well beyond current bounds at a single frequency. Future improvements include enhancing the sensitivity of the resonator and improved cavity shape.
