Tunable localization of light using nested invisible metasurface cavities

open access: yesNanophotonics, Volume 12, Issue 6, Page 1083-1089, March 2023., 2023
Abstract An invisible cavity is an open resonant device that confines a localized field without producing any scattering outside of the device volume. By exploiting the scatter‐less property of such device, it is possible to nest two invisible cavities, as the outer cavity would simply not notice the presence of the inner one, regardless of their ...

Searching for wave-like dark matter with QSHS

open access: yesSciPost Physics Proceedings, 2023
In 2021 the Quantum Sensors for the Hidden Sector (QSHS) collaboration was founded in the UK and received funding to develop and demonstrate quantum devices with the potential to detect hidden sector particles in the $\mu$eV to 100 $\mu$eV mass window ...

Axion haloscope array with PT symmetry

open access: yesPhysical Review Research, 2022
We generalize the recently proposed PT-symmetric axion haloscope to a larger array with more PT-symmetric structures. By broadening the response bandwidth of the signal without increasing the readout noise, the optimized scan rate of the axion haloscope ...

First Axion Dark Matter Search with Toroidal Geometry [PDF]

open access: yes, 2017
We report the first axion dark matter search with toroidal geometry. Exclusion limits of the axion-photon coupling $g_{a\gamma\gamma}$ over the axion mass range from 24.7 to 29.1 $\mu$eV at the 95\% confidence level are set through this pioneering search.

Methods and restrictions to increase the volume of resonant rectangular-section haloscopes for detecting dark matter axions

open access: yesJournal of High Energy Physics, 2023
Haloscopes are resonant cavities that serve as detectors of dark matter axions when they are immersed in a strong static magnetic field. In order to increase the volume and improve space compatibility with dipole or solenoid magnets for axion searches ...

Design of New Resonant Haloscopes in the Search for the Dark Matter Axion: A Review of the First Steps in the RADES Collaboration

open access: yesUniverse, 2021
With the increasing interest in dark matter axion detection through haloscopes, in which different international groups are currently involved, the RADES group was established in 2016 with the goal of developing very sensitive detection systems to be ...

MADMAX: A Dielectric Haloscope Experiment [PDF]

open access: yesProceedings of 40th International Conference on High Energy physics — PoS(ICHEP2020), 2020
Abstract Axions emerge naturally from the Peccei-Quinn mechanism, which addresses the absence of CP violation in the strong interaction, and they can make up the cold dark matter (CDM) in the universe. If PQ symmetry was broken after inflation, the CDM axion mass would likely be in the range of ˜ 26 μeV to ˜ 1 meV, which is yet to be ...

Revisiting the detection rate for axion haloscopes [PDF]

open access: yesJournal of Cosmology and Astroparticle Physics, 2020
The cavity haloscope has been employed to detect microwave photons resonantly converted from invisible cosmic axions under a strong magnetic field. In this scheme, the axion-photon conversion power has been formulated to be valid for certain conditions, either Q cavity ≪ Q axion or Q cavity ≫ Q

High-availability on-site deployment to heterogeneous architectures for Project 8 and ADMX [PDF]

open access: yesEPJ Web of Conferences, 2020
Project 8 is applying a novel spectroscopy technique to make a precision measurement of the tritium beta-decay spectrum, resulting in either a measurement of or further constraint on the effective mass of the electron antineutrino.
