Dynamically tuneable helicity in twisted electromagnetic resonators
E. C. I. Paterson, J. Bourhill, M. E. Tobar +1
We report the generation of helical electromagnetic radiation in a microwave cavity resonator, achieved by introducing mirror asymmetry, i.e., chirality, through a controlled geome…
Distinct Berry Phases in a Single Triangular Möbius Microwave Resonator
E. C. I. Paterson, M. E. Tobar, M. Goryachev +1
We report the experimental observation of two distinct Berry phases ( and ) generated on the surface of a Möbius cavity resonator at microwave freq…
Search for Axion Dark Matter from 1.1 to 1.3 GHz with ADMX
ADMX Collaboration, G. Carosi, C. Cisneros +50
Axion dark matter can satisfy the conditions needed to account for all of the dark matter and solve the strong CP problem. The Axion Dark Matter eXperiment (ADMX) is a direct dark…
Electromagnetic Helicity in Twisted Cavity Resonators
E. C. I. Paterson, J. Bourhill, M. E. Tobar +1
Through left- or right-handed twisting, we investigate the impact of mirror-asymmetry (chirality) of the conducting boundary conditions of an equilaterial triangular cross-section…
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…
