The DALI Haloscope: A Magnetized Phased Array Coupled to a Semi-Open Fabry--Pérot Resonator
Javier De Miguel, Antonios Gardikiotis, Eduardo David González-Carretero +10
DALI is an axion haloscope consisting of a magnetized phased array backed by a conducting mirror and coupled in the near field to a semi-open Fabry--Pérot resonator. The applied st…
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…
Microwave Studies of Single Crystal TeO2 at Cryogenic Temperatures
Timothy Holt, Maxim Goryachev, William Campbell +1
We use whispering-gallery-mode analysis to characterise the microwave dielectric properties of single-crystal TeO at cryogenic temperatures and compare its loss performance wit…
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…
Coupling 4H-Silicon Carbide spins to a microwave resonator at milli-Kelvin temperature
Ali Fawaz, Jeremy Bourhill, Stefania Castelletto +6
Coupling microwave cavity modes with spin qubit transitions is crucial for enabling efficient qubit readout and control, long-distance qubit coupling, quantum memory implementation…
Sharp electromagnetically induced absorption via balanced interferometric excitation in a microwave resonator
Michael Hatzon, Graeme Flower, Maxim Goryachev +2
A cylindrical TM mode microwave cavity resonator was excited using a balanced interferometric configuration that allowed manipulation of the electric field and potential…
