The quantum limits of sensing for ultralight dark matter detection (B10*)

• Subject Area: Optics, Quantum Optics and Physics of Atoms, Molecules and Plasmas
• Term: since 2024
• Project identifier: Deutsche Forschungsgemeinschaft (DFG) - Project number 274200144

The sensitive measurement of the electromagnetic field plays a crucial role in many high-energy physics (HEP) experiments, including, the measurement of the coupling of ultralight dark matter (DM) candidates, including, axions and dark photons, to the electromagnetic sector. The goal of this project is to investigate the fundamental limits of sensing and to develop experimental proposals to reach these limits in parameter regimes relevant for ultralight dark matter searches. Furthermore, optimal detection schemes for new candidates for DM are to be explored.
