76. Status and recent developments of the QUAX haloscope at Legnaro National Laboratories

The QUaerere AXion (i.e. QUest for AXions, in short QUAX) experiment is an haloscope-based galactic axion search effort aiming to probe theoretically-relevant axion-photon couplings in the 8.5-11 GHz frequency window.
This frequency range will be covered by two haloscope setups, located at LNL- and LNF-INFN laboratories in Italy respectively. In this talk we will focus on the recent results...

41. SUPAX - A Superconducting Axion Search Experiment

SUPAX is one of the first RF cavity based experiments in Germany to search for axions. Axions could solve the well known strong CP problem and may explain the dark matter content of the universe.
Axions are expected to convert to photons in the presence of a strong magnetic field, where the photon frequency depends on the axions mass. For wavelengths in the microwave regime resonators are...

49. Ultra-high Q cavity-based search for the Dark Photon: new exclusion limit from Dark SRF phase 1 and steps forward for phase 2

Bianca Giaccone (Fermilab)

We present here the first results of Dark SRF, a light-shining-through-wall (LSW) experiment that leverages ultra-high quality factor superconducting radio frequency (SRF) cavities to search for dark photons. The use of Nb SRF cavities combined with a strict calibration and measurement protocol increased sensitivity to dark photons by several orders of magnitude compared to other LSW...

29. Dark Matter detection with Qubits

Dark Matter searches utilizing single-photon and phonon excitations have been broadly accepted as effective methods of harnessing the miniscule energies transferred from Ultra-light and Light Dark Matter. Qubits are highly sensitive to sub-eV energy phonons and photons which make them a compelling detection technology for light and Ultralight Dark Matter. We will discuss the potential of this...

79. JUNO's Quest: The Hunt for Solar Axions

Newton Nath (Istituto Nazionale di Fisica Nucleare)

We shall discuss the 5.49 MeV solar axions flux produced in the $p(d,$ $\!\! ^3{\rm He})a$ reaction and analyze the potential to detect it with the forthcoming large underground neutrino oscillation experiment Jiangmen Underground Neutrino Observatory (JUNO). In doing so, we will consider axions through various processes such as Compton and inverse Primakoff conversion, as well as through...
