UPLOAD-ANYON: Progress Towards an Optimised Twisted Anyon Cavity with High-Sensitivity AM-Noise Detection for an Ultralight Axion Dark Matter Search
Robert Crew, Emma Paterson, Maxim Goryachev +5
We propose a superconducting single-mode microwave haloscope based on helical cavity resonators for the detection of ultralight dark matter axions over the mass range to…
Coupling phase interference effects in a multimode cavity magnonics system
M. Avicena, G. Bourcin, V. Vlaminck +2
Coupling phases play a decisive yet often overlooked role in cavity magnonics, particularly in complex multimode systems. Here, we investigate phase-mediated interference effects i…
Probing Light-Matter Interaction with Topological Data Analysis
Timothy Holt, Maxim Goryachev, Jeremy Bourhill
We explore application of Topological Data Analysis to study light matter interaction through scattering response data in different dimensions. This method is robust against Fano r…
Multi-mode input-output model for cavity magnonics: phase-resolved control of level repulsion, level attraction, and nonreciprocal transmission
Guillaume Bourcin, Mufti Avicena, Vincent Vlaminck +2
We experimentally validate a unified input--output model that incorporates internal and external coupling phases across multiple cavity modes in a room-temperature cavity magnonic…
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…
Inverse Design of Three-Dimensional Microwave Cavities for Optimizing Electromagnetic Helicity
Emma Paterson, Jeremy Bourhill, Maxim Goryachev
We present a inverse-design framework framework for systematically engineering three-dimensional microwave cavity resonators that support modes with nonzero electromagnetic helicit…
