DMRadio-Core: A new approach for GUT-scale axion searches
V. Ankel, C. Bartram, J. Begin +33
Searches for QCD axions with masses in the neV/ mass range are strongly motivated by new physics at the GUT scale and by well-motivated pre-inflationary axion symmetry breakin…
Search for Axion Dark Matter from 1.1 to 1.3 GHz with ADMX
ADMX Collaboration, G. Carosi, C. Cisneros +50
Axion dark matter can satisfy the conditions needed to account for all of the dark matter and solve the strong CP problem. The Axion Dark Matter eXperiment (ADMX) is a direct dark…
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…
Electromagnetic modeling and science reach of DMRadio-m
DMRadio Collaboration, A. AlShirawi, V. Ankel +45
DMRadio-m is an experiment that is designed to be sensitive to KSVZ and DFSZ QCD axion models in the 10--200\,MHz (41 neV -- 0.83 eV/) range. The experiment uses…
Improved Receiver Noise Calibration for ADMX Axion Search: 4.54 to 5.41 eV
M. Guzzetti, D. Zhang, C. Goodman +48
Axions are a well-motivated candidate for dark matter. The preeminent method to search for axion dark matter is known as the axion haloscope, which makes use of the conversion of a…
