Extended Axion Dark Matter Search Using the CAPP18T Haloscope

Physical Review Letters, 2023
We report an extended search for the axion dark matter using the CAPP18T haloscope. The CAPP18T experiment adopts innovative technologies of a high-temperature superconducting magnet and a Josephson parametric converter. The CAPP18T detector was reconstructed after an unexpected incident of the high-temperature superconducting magnet quenching.

Progress in GrAHal-CAPP/DMAG for Axion Dark Matter Search in the 1–3 μeV Range

Physical Sciences Forum
Two outstanding problems of particle physics and cosmology, namely the strong-CP problem and the nature of dark matter, can be solved with the discovery of a single new particle, the axion.

Limits on Dark Photons, Scalars, and Axion‐Electromagnetodynamics with the ORGAN Experiment

Annalen der Physik, Volume 536, Issue 1, January 2024.
The nature of dark matter is one of the biggest mysteries in the Universe. ORGAN is an experiment which seeks to understand dark matter by figuring out what it is made of. In this article, the current sensitivity of ORGAN to various promising dark matter candidates is presented, and the future sensitivity is projected.

Cavity, Lumped Circuit, and Spin-Based Detection of Axion Dark Matter: Differences and Similarities

Universe
Axions and axion-like particles are compelling candidates for ultralight bosonic dark matter, forming coherent oscillating fields that can be probed by experiments known as haloscopes.

Generic Axion Maxwell Equations: Path Integral Approach

Annalen der Physik, Volume 536, Issue 1, January 2024.
It is possible that the interactions between axions and electromagnetic field are mediated by heavy dyons. In this article, the corresponding axion Maxwell equations are derived using the path integral approach. These equations feature novel axion‐dependent terms which can lead to unique signatures in light‐shining‐through‐wall and haloscope ...

A Quantum Perspective on Oscillation Frequencies in Axion Dark Matter Experiments

Annalen der Physik, Volume 536, Issue 1, January 2024.
The time evolution of signals in axion dark matter experiments, such as CASPEr, is looked at from a quantum perspective. Classically, one expects signals oscillating with a frequency equal to the axion mass. The explanation of where this oscillation frequency appears from a quantum perspective and how it relates to the axion quantum state. The suitable

A Search for Dark Matter Axions with the Orpheus Experiment

, 2015
Axions are well motivated particles that could make up most or all of the dark matter if they have masses below 100 $\mu$eV. Microwave cavity techniques comprised of closed resonant structures immersed in solenoid magnets are sensitive to dark matter ...

A new experimental approach to probe QCD axion dark matter in the mass range above $${ 40}\,{\upmu }\mathrm{{eV}}$$ 40μeV

European Physical Journal C: Particles and Fields, 2019
The axion emerges in extensions of the Standard Model that explain the absence of CP violation in the strong interactions. Simultaneously, it can provide naturally the cold dark matter in our universe. Several searches for axions and axion-like particles
