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 frequen…
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…
Upconversion of Phonon Modes into Microwave Photons in a Lithium Niobate Bulk Acoustic Wave Resonator Coupled to a Microwave Cavity
S. Parashar, W. M. Campbell, J. Bourhill +3
The coupling between acoustic vibrations in a lithium niobate bulk acoustic wave resonator and microwave photons of a re-entrant microwave cavity was investigated at a temperature…
Search for non-virialized axions with 3.3-4.2 eV mass at selected resolving powers
A. T. Hipp, A. Quiskamp, T. J. Caligiure +65
The Axion Dark Matter eXperiment is sensitive to narrow axion flows, given axions compose a fraction of the dark matter with a non-negligible local density. Detecting these low-vel…
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…
Non-Virialized Axion Search Sensitive to Doppler Effects in the Milky Way Halo
C. Bartram, T. Braine, R. Cervantes +53
The Axion Dark Matter eXperiment (ADMX) has previously excluded Dine-Fischler-Srednicki-Zhitnisky (DFSZ) axions between 680-790 MHz under the assumption that the dark matter is des…
Tunable Rectangular Resonant Cavities for Axion Haloscopes
Ben T. McAllister, Aaron P. Quiskamp, Michael E. Tobar
Axions are a compelling dark matter candidate, and one of the primary techniques employed to search for them is the axion haloscope, in which a resonant cavity is deployed inside a…
Axion Dark Matter
C. B. Adams, N. Aggarwal, A. Agrawal +152
Axions are well-motivated dark matter candidates with simple cosmological production mechanisms. They were originally introduced to solve the strong CP problem, but also arise in a…
Search for "Invisible" Axion Dark Matter in the eV Mass Range
ADMX Collaboration, C. Bartram, T. Braine +49
We report the results from a haloscope search for axion dark matter in the eV mass range. This search excludes the axion-photon coupling predicted by one of the b…
Dark Sectors and New, Light, Weakly-Coupled Particles
R. Essig, J. A. Jaros, W. Wester +86
Dark sectors, consisting of new, light, weakly-coupled particles that do not interact with the known strong, weak, or electromagnetic forces, are a particularly compelling possibil…
Long-distance frequency dissemination with a resolution of 10-17
Christophe Daussy, Olivier Lopez, Anne Amy-Klein +11
We use a new technique to disseminate microwave reference signals along ordinary optical fiber. The fractional frequency resolution of a link of 86 km in length is 10-17 for a one…
