Stefan Schäffer leads the Quantum Metrology group at NBI together with Jörg Müller. Research focuses on superradiant strontium lasers: (1) quasi-continuous superradiant lasing with sub-natural linewidth; (2) Ramsey spectroscopy enhanced by cavity sub-to-superradiant phase transitions for improved atomic clock sensing; (3) continuous atom beam for Dicke-effect-free superradiant interrogation. Key work published in PRL (2023) and Nature Communications (2024). Part of EU iqClock and ESA collaborations.

Scully directs IQSE and pursues foundational quantum optics: quantum coherence effects (lasing without inversion, electromagnetically induced transparency), collective/superradiant emission, quantum-enhanced spectroscopy, and coherent-Raman schemes (FAST CARS) for real-time detection of pathogens and molecular fingerprints. In the broader landscape of NV-centre ensemble quantum sensing (DEER, nano-NMR, T1 relaxometry) operating near pT/sqrt(Hz) sensitivity, this work sits on the fundamental-light side, providing coherence and superradiance concepts that inform quantum-enhanced magnetometry read-out.

Yelin is a theorist in quantum optics and quantum information whose work includes coherent line-narrowing theory for diamond NV centers, superradiant/cooperative effects in Rydberg systems and molecular ensembles, and quantum control of ultracold polar molecules. Included as theoretical support underpinning several quantum-sensing platforms (NV coherence, superradiant clocks) rather than as an experimentalist herself; she holds a joint appointment at the University of Connecticut.
