Jacqueline Bloch leads a world-leading group on semiconductor exciton-polariton physics at C2N/Paris-Saclay. Research: (1) polariton condensation and quantum fluids of light — superfluidity, vortices, analogue gravity; (2) topological insulator physics with polaritons; (3) quantum simulation with polariton lattices; (4) fundamental quantum optics of polariton systems. IQUPS co-organiser; C2N head. Key for light-physics sensing relevant to quantum fluids and topological photonics.

Bramati leads the Quantum Fluids of Light team at LKB, studying exciton-polariton superfluids in semiconductor microcavities: quantized vortices, dark solitons, half-solitons behaving as magnetic monopoles, and analogue-gravity phenomena in polariton and photon fluids. The group also develops single-photon sources based on nanoemitters and coordinates the international Q-GAP program with Singapore's NRF on quantum fluids and photonics.

Cherroret develops the theory of multiple light scattering, Anderson localization, and quantum-fluid-of-light phenomena in disordered polariton/photonic systems, supporting the experimental polariton-fluid programme led by Alberto Bramati's team.

Quentin Glorieux's group explores quantum fluids of light and polariton physics. Research: (1) exciton-polariton condensates in semiconductor microcavities — superfluidity, vortex dynamics, analogue gravity; (2) quantum fluids of light in atomic media — photon-photon interactions via electromagnetically induced transparency; (3) analogue gravity with polariton and photon fluids — studying acoustic black hole analogs with quantum light. IUF member; ERC grants.

Simon's lab engineers strong, atom-mediated interactions between photons in optical cavities -- using Rydberg dressing of intracavity atoms -- to synthesize interacting quantum photonic matter and study fundamental nonclassical light phenomena, effectively building tunable many-body systems out of light itself.
