UPLOAD-ANYON: Progress Towards an Optimised Twisted Anyon Cavity with High-Sensitivity AM-Noise Detection for an Ultralight Axion Dark Matter Search
Robert Crew, Emma Paterson, Maxim Goryachev +5
We propose a superconducting single-mode microwave haloscope based on helical cavity resonators for the detection of ultralight dark matter axions over the mass range to…
A Search for Effects of Cosmic Rays with Multi-scale Entropy Metrics
William M. Campbell, Ben T. McAllister, Eugene N. Ivanov +4
We report a comparison of frequency fluctuations in oven-controlled quartz bulk-acoustic-wave oscillators operated above ground and one kilometre underground in a low-muon-backgrou…
The Study of Thermal Fluctuations in Microwave and Mechanical Resonators
Michael T Hatzon, Eugene N Ivanov, Aaron Quiskamp +1
We report high-resolution measurements of thermal fluctuations in microwave and mechanical resonators using a dual-channel readout system. The latter comprises a low-noise amplifie…
Near-quantum-limited axion dark matter search with the ORGAN experiment around 26 eV
Aaron P. Quiskamp, Graeme Flower, Steven Samuels +5
The latest result from the ORGAN experiment, an axion haloscope is presented. This iteration of the experiment operated at millikelvin temperatures using a flux-driven Josephson pa…
