Sapienza studies light propagation and control in complex/disordered nanophotonic media, using wavefront shaping and transmission-matrix approaches to focus and image through scattering media, with applications to deep-tissue fluorescence imaging and nanophotonic light sources.
Sapienza's Integrated Quantum Photonics group studies quantum optics on a chip, developing nanophotonic devices that integrate solid-state single-photon emitters (III-V quantum dots) with photonic crystal and plasmonic cavities, alongside investigations of quantum effects in biomolecules.
Sauer co-leads both YbF eEDM experiments at the Centre for Cold Matter together with Tarbutt and Lim. Key contributions: magnetometry for EDM measurement (design and characterisation of precision magnetic field systems for the ultracold eEDM experiment), precision spectroscopy of heavy polar molecules (YbF, lattice eEDM), and development of spin polarisation/analysis schemes. Co-PI on STFC grants for eEDM and magnetometry. Together the group aims to probe the eEDM at the 10^−30 e·cm level — several orders of magnitude improvement over existing measurements from ACME (Harvard/Yale).
Sayrin works on circular Rydberg-atom cavity QED at LKB, developing microwave-photon quantum-non-demolition detection and feedback-based quantum control protocols that build on the cavity-QED foundations pioneered by Haroche and Brune's team.
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.
Marie-Claire Schanne-Klein (DR1 CNRS, LOB) specializes in polarized SHG and THG microscopy for structural tissue imaging. Research: (1) polarimetric SHG imaging of collagen fibril organization — molecular orientation mapping; (2) THG microscopy for myelin and red blood cell imaging; (3) structural and functional label-free imaging of connective tissues; (4) multi-scale SHG/THG analysis of biopolymer structure. SHG expert in LOB.
Uses single-molecule spectroscopy, optical trapping, and advanced imaging to study nanoscale systems. Directions: (1) orientation-resolved single-molecule spectroscopy using polarization-controlled excitation and detection; (2) optical trapping of individual nanoparticles and viruses to study force-dependent dynamics; (3) plasmon-enhanced single-molecule detection and imaging beyond diffraction limit; (4) ultrafast spectroscopy of nanoscale energy transfer.
Schermelleh develops and applies 3D structured-illumination and correlative super-resolution/cryo-EM microscopy to study spatial genome architecture, investigating how biophysical forces, epigenetic memory and cohesin activity shape cell-type-specific transcription programmes at the nanoscale; he directs the Micron Oxford Advanced Bioimaging Facility.
Schleier-Smith's group uses optical-cavity-mediated interactions to entangle and spin-squeeze ensembles of trapped neutral atoms, generating metrologically useful entangled states for quantum-enhanced sensing, and is developing modular, networked atom-cavity systems as building blocks for distributed quantum sensor arrays and simulators.
Albert Schliesser's group engineers ultracoherent phononic crystal membrane resonators with dissipation-dilution Q>10^9 and uses them for quantum optomechanics: ground-state cooling, back-action-evading measurement, optical quantum memory for single photons, and microwave-optical quantum transduction. Recent work has demonstrated a soft-clamped topological phononic waveguide (Nature 2025) and scanning force microscopy below the standard quantum limit. The group bridges fundamental quantum physics with novel sensors for electromagnetic fields and forces, and mechanical interfaces for hybrid quantum networks.
