Extended Haloscope Search and Exclusion of a Candidate Signal near 1.036 GHz
Saebyeok Ahn, Boris I. Ivanov, Ohjoon Kwon +33
We report a follow-up axion haloscope search near 1.036 GHz that completes and extends our previous work [Phys. Rev. X 14, 031023 (2024)], in which a portion of the HEMT-based data…
Axion dark matter searches from the standard halo over the tidal stream to the big flow
Andrew K. Yi, Byeong Rok Ko
The sensitivity of axion dark matter searches depends on the signal window that results from the velocity dispersion of axion dark matter. Since the ratio of signal windows is abou…
Asymmetrical cavity design that bypasses mode mixings in axion haloscope experiments
Byeong Rok Ko, Andrew K. Yi
Microwave cavities used in axion haloscope experiments typically employ a tuning rod as a means to widen the range of resonance frequencies at which it is sensitive to axion-to-pho…
Maximizing Quantum Enhancement in Axion Dark Matter Experiments
Chao-Lin Kuo, Chelsea L. Bartram, Aaron S. Chou +8
We provide a comprehensive comparison of linear amplifiers and microwave photon-counters in axion dark matter experiments. The study is done assuming a range of realistic operating…
