Sylvain Ravets

Sylvain Ravets is a tenured CNRS Researcher and Principal Investigator (PI) of the ERC Starting Grant ARQADIA at the Centre for Nanosciences and Nanotechnology (C2N), Université Paris-Saclay. He leads the Quantum Polaritonic Matter group, focusing on manipulating quantum light in semiconductor nanostructures to develop artificial quantum materials. His work bridges condensed matter physics and quantum optics, with applications in photonics and quantum technologies.

Education:

• PhD in Physics (2011-2014): Joint Quantum Institute (University of Maryland, USA) and Laboratoire Charles Fabry (Institut d'Optique, France).
• Master's and Bachelor's Degrees: Ecole Normale Supérieure de Cachan, France.

Research Interests: Quantum polaritons, semiconductor nanostructures, quantum fluids of light, topological photonics, and driven-dissipative many-body quantum systems. His ERC-funded project ARQADIA explores synthetic quantum materials using polaritons to simulate complex phenomena like superfluidity and topological phases.

Key Contributions:

• Discovered KPZ universality in polariton condensates, linking quantum optics to stochastic growth models.
• Developed methods for eigenstate tomography in polariton lattices and engineered topological phases in photonic systems.
• Pioneered studies on nonlinear optics in fractional quantum Hall regimes using semiconductor microcavities.

Awards:

• ERC Starting Grant (2020)
• Finalist, Carl E. Anderson Award (2016)
• ETH Postdoctoral Fellowship (2015-2017)

Collaborations: Leads an interdisciplinary team with ties to institutions like ETH Zurich, Université Grenoble Alpes, and University of Sheffield. Active in international networks like GDR TEQ and IQFA.

Teaching: Teaches advanced courses on quantum optics and nanophotonics at Université Paris-Saclay, and mentors students from Ecole Polytechnique in lab projects (PSC/PRL).
