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…
Follow-up Search for a Tentative Dark Photon Signal Near 19.5 eV using ORGAN-Q infrastructure
Aaron P. Quiskamp, Graeme R. Flower, Maxim Goryachev +2
A recent independent dark photon (DP) focused reanalysis of existing data from the TASEH axion haloscope experiment reported a tentative DP dark matter signal with local significan…
Dielectric Properties of Single Crystal Calcium Tungstate
Elrina Hartman, Michael E Tobar, Ben T McAllister +3
This investigation employed microwave whispering gallery mode (WGM) analysis to characterize the dielectric properties of a cylindrical, single-crystal sample of calcium tungstate…
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…
Conductivity Freeze-Out in Isotopically Pure Si-28 at milli-Kelvin Temperatures
Ben T. McAllister, Zijun C. Zhao, Jeremy F. Bourhill +4
Silicon is a key semiconducting material for electrical devices and hybrid quantum systems where low temperatures and zero-spin isotopic purity can enhance quantum coherence. Elect…
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…
