Foil-Mediated Mutual-Impedance in Microwave Cavities with Enhanced Phase Response
Michael T. Hatzon, Graeme R. Flower, Robert C. Crew +4
We formulate and validate an equivalent circuit model describing mutual coupling between three microwave cavity resonators interconnected via thin metallic foils. Each cavity is re…
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…
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…
Scalar Gravitational Aharonov-Bohm Effect: Generalization of the Gravitational Redshift
Michael E Tobar, Michael T Hatzon, Graeme R Flower +1
The Aharonov-Bohm effect is a quantum mechanical phenomenon that demonstrates how potentials can have observable effects even when the classical fields associated with those potent…
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…
Determination of Niobium Cavity Magnetic Field Screening via a Dispersively Hybridized Magnonic Sensor
Graeme Flower, Benjamin McAllister, Maxim Goryachev +1
A method for determining the internal DC magnetic field inside a superconducting cavity is presented. The method relies on the relationship between magnetic field and frequency of…
Experimental Implementations of Cavity-Magnon Systems: from Ultra Strong Coupling to Applications in Precision Measurement
Graeme Flower, Maxim Goryachev, Jeremy Bourhill +1
Several experimental implementations of cavity-magnon systems are presented. First an Yttrium Iron Garnet (YIG) block is placed inside a re-entrant cavity where the resulting hybri…
Broadening Frequency Range of a Ferromagnetic Axion Haloscope with Strongly Coupled Cavity-Magnon Polaritons
Graeme Flower, Jeremy Bourhill, Maxim Goryachev +1
With the axion being a prime candidate for dark matter, there has been some recent interest in direct detection through a so called `Ferromagnetic haloscope.' Such devices exploit…
The ORGAN Experiment: An axion haloscope above 15 GHz
Ben T. McAllister, Graeme Flower, Justin Kruger +4
We present first results and future plans for the Oscillating Resonant Group AxioN (ORGAN) experiment, a microwave cavity axion haloscope situated in Perth, Western Australia desig…
Tunable Super-Mode Dielectric Resonators for Axion Haloscopes
Ben T. McAllister, Graeme Flower, Lucas E. Tobar +1
We present frequency tuning mechanisms for dielectric resonators, which undergo "super-mode" interactions as they tune. The tunable schemes are based on dielectric materials strate…
Higher Order Reentrant Post Modes in Cylindrical Cavities
Ben T. McAllister, Yifan Shen, Graeme R. Flower +2
Reentrant cavities are microwave resonant devices employed in a number of different areas of physics. They are appealing due to their simple frequency tuning mechanism, which offer…
