The advent of quantum-enhanced sensing methods in axion dark matter searches holds the promise of surpassing the quantum-limited scan rate by an order of magnitude or more. Superconducting circuits enable the generation of squeezed states in axion haloscopes and the direct detection of microwave photons. But the strong magnetic fields required in axion haloscopes complicate the use of...

The nature of dark matter remains one of the greatest mysteries in physics. While traditional axion searches rely on resonator-based experiments with narrow bandwidths, the next frontier in detection demands a broader, more efficient approach. Our research on the graphene-based single-photon bolometer aims to revolutionize this search by developing an unprecedented single-photon detector with...

The interaction with the electromagnetic field is the most exploited in haloscopes, detectors where axions are resonantly converted into photons in the presence of an intense magnetic field. Some models also predict interaction with electron spin, which can be probed using a ferrimagnetic haloscope. In this detector, hypothetical particles are converted into magnons in a material with specific...
