UPLOAD-HELIX: High-Helicity Single-Mode Microwave Haloscope with Low-Noise Interferometric Readout for Ultralight Axion Dark Matter
Robert C. Crew, Emma C. I. Paterson, Maxim Goryachev +5
We propose a superconducting single-mode microwave haloscope based on chiral cavity resonators for the detection of ultralight dark matter axions over the mass range $4\times10^{-1…

Equivalent Circuit Modeling of Foil-Mediated Dissipative Coupling in Microwave Cavities with Enhanced Phase Response
Michael T. Hatzon, Graeme R. Flower, Robert C. Crew +2
We formulate and validate an equivalent circuit model describing mutual resistive coupling between three microwave cavity resonators interconnected via thin metallic foils. Each ca…
