A quantum-enhanced search for dark matter axions
K. M. Backes, D. A. Palken, S. Al Kenany +21
In dark matter axion searches, quantum uncertainty manifests as a fundamental noise source, limiting the measurement of the quadrature observables used for detection. We use vacuum…
Resonant Conversion of Dark Matter Oscillons in Pulsar Magnetospheres
Anirudh Prabhu, Nicholas M. Rapidis
Due to their high magnetic fields and plasma densities, pulsars provide excellent laboratories for tests of beyond Standard Model (BSM) physics. When axions or axion-like particles…
An improved analysis framework for axion dark matter searches
D. A. Palken, B. M. Brubaker, M. Malnou +17
In experiments searching for axionic dark matter, the use of the standard threshold-based data analysis discards valuable information. We present a Bayesian analysis framework that…
Completion of Phase I and Preparation for Phase II of the HAYSTAC Experiment
Nicholas M. Rapidis
The HAYSTAC experiment utilizes a tunable resonant microwave cavity to search for dark matter axions. We report on the system and the results from Phase I of the experiment. This p…
Characterization of the HAYSTAC axion dark matter search cavity using microwave measurement and simulation techniques
Nicholas M. Rapidis, Samantha M. Lewis, Karl A. van Bibber
Many searches for axion cold dark matter rely on the use of tunable electromagnetic resonators. Current detectors operate at or near microwave frequencies and use cylindrical cavit…
Results from phase 1 of the HAYSTAC microwave cavity axion experiment
L. Zhong, S. Al Kenany, K. M. Backes +18
We report on the results from a search for dark matter axions with the HAYSTAC experiment using a microwave cavity detector at frequencies between 5.6-5.8. We exclude a…
