Search for Dark Photons between 16.96--19.52 eV with the HAYSTAC Experiment
Xiran Bai, A. Droster, J. Echevers +21
We report dark photon results from HAYSTAC Phase II using data from previously reported axion searches. Additionally, we present an analysis of an unpublished dataset covering a re…

Rydberg-atom-based single-photon detection for haloscope axion searches
Eleanor Graham, Sumita Ghosh, Yuqi Zhu +8
We propose a Rydberg-atom-based single-photon detector for signal readout in dark matter haloscope experiments between 40 eV and 200 eV (10 GHz and 50 GHz). At these frequenc…
