Description
The QROCODILE (Quantum Resolution-Optimized Cryogenic Observatory for Dark matter Incident at Low Energy) experiment uses superconducting nanowire single-photon detectors (SNSPDs) to search for scattering and absorption of dark matter (DM) candidates with masses as low as 30 keV. We conducted a first measurement at the University of Zurich with a WSi SNSPD placed on a Si/SiO2 substrate, and we set new world-leading constraints for DM-electron scattering, DM-nucleon scattering and electronic absorption of dark photons. In this presentation I will discuss the working principle, recent results and future plans of QROCODILE.
