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…
Detecting kHz gravitons from a neutron star merger with a multi-mode resonant mass detector
Germain Tobar, Igor Pikovski, Michael Edmund Tobar
We propose a multi-mode bar consisting of mass elements of decreasing size for the implementation of a gravitational version of the photo-electric effect through the stimulated abs…
Precision Multi-Mode Microwave Spectroscopy of Paramagnetic and Rare-Earth Ion Spin Defects in Single Crystal Calcium Tungstate
Elrina Hartman, Michael E Tobar, Ben T McAllister +2
We present experimental observations of dilute ion spin ensemble defects in a low-loss single crystal cylindrical sample of CaWO cooled to mK in temperature. Crystal field…
Metallised 3D printed plastic resonator demonstrates superconductivity below 4 K
Jeremy Bourhill, Gwendal Cochet, Julien Haumant +4
We report the first observation of a superconducting transition in a 3D printed, metallised-plastic device. A cylindrical cavity is 3D printed from a photosensitive polymer resin a…
Sensitivity Characterisation of a Parametric Transducer for Gravitational Wave Detection Through Optical Spring Effect
N. C. Carvalho, O. D. Aguiar, J. Bourhill +1
We present the characterisation of the most recent parametric transducers designed to enhance the Mario Schenberg Gravitational Wave Detector sensitivity. The transducer is compose…
Acoustic tests of Lorentz symmetry using Bulk Acoustic Wave quartz oscillators
M. Goryachev, A. Lo, Ph. Haslinger +5
A new method of probing Lorentz invariance in the neutron sector is described. The method is baed on stable quartz bulk acoustic wave oscillators compared on a rotating table. Due…
Spin bath maser in a cryogenically cooled sapphire whispering gallery mode resonator
J. Bourhill, K. Benmessai, M. Goryachev +3
We report the observation of a mechanism of maser generation in an ensemble of inter-coupled, inhomogeneously broadened two-level systems, enhanced by high quality factor electroma…
