Improved axion haloscope search analysis [PDF]

Journal of High Energy Physics, 2021
One of the most significant and practical figures of merit in axion haloscope searches is the scanning rate, because of the unknown axion mass. Under the best experimental parameters, the only way to improve the figure of merit is to increase the ...

Axion Search with a Quantum-Limited Ferromagnetic Haloscope [PDF]

Physical Review Letters, 2020
A ferromagnetic axion haloscope searches for Dark Matter in the form of axions by exploiting their interaction with electronic spins. It is composed of an axion-to-electromagnetic field transducer coupled to a sensitive rf detector.

The ORGAN experiment: An axion haloscope above 15 GHz [PDF]

Physics of the Dark Universe, 2017
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 designed to probe for high mass axions motivated by several theoretical models.

Long-baseline quantum sensor network as dark matter haloscope. [PDF]

Nat Commun
Ultralight dark photons constitute a well-motivated candidate for dark matter. A coherent electromagnetic wave is expected to be induced by dark photons when coupled with Standard-Model photons through kinetic mixing mechanism, and should be spatially ...

A first proof of principle booster setup for the MADMAX dielectric haloscope

European Physical Journal C: Particles and Fields, 2020
Axions and axion-like particles are excellent low-mass dark matter candidates. The MADMAX experiment aims to directly detect galactic axions with masses between 40 and $$400\,\upmu \mathrm{eV}$$ 400μeV by using the axion-induced emission of ...

Split-cavity tuning of a rectangular axion haloscope operating around 8.4 GHz

Frontiers in Physics
The axion haloscope is the currently most sensitive method to probe the vanishingly small coupling of this prominent Dark Matter candidate to photons. To scan a sizeable axion Dark Matter parameter space, the cavities that make up the haloscope need to ...

The search of Axion Dark Matter with a dielectric halo-scope: MADMAX [PDF]

EPJ Web of Conferences, 2023
The strong CP problem is one of the most fundamental unresolved questions in the standard model of particle physics. The axion, emerging due to the maybe most elegant solution to the strong CP problem, could also solve the long standing dark matter ...

On the Development of New Tuning and Inter-Coupling Techniques Using Ferroelectric Materials in the Detection of Dark Matter Axions

IEEE Access, 2023
Tuning is an essential requirement for the search of dark matter axions employing haloscopes since its mass is not known yet to the scientific community.

Enhancing resonant circular-section haloscopes for dark matter axion detection: approaches and limitations in volume expansion

Journal of High Energy Physics, 2023
Haloscopes, microwave resonant cavities utilized in detecting dark matter axions within powerful static magnetic fields, are pivotal in modern astrophysical research. This paper delves into the realm of cylindrical geometries, investigating techniques to
