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.

Glorieux leads the Quantum Fluids of Light and Nanophotonics group at LKB. Research directions: (1) Quantum fluids of light in atomic vapors — hot Rb/Cs vapor as paraxial photon fluids exhibiting superfluidity, soliton dynamics, and vortex formation; first analogue cosmological particle creation (Hawking effect) in a photon fluid (Nature Communications 2022); (2) Polariton superfluids — exciton-polariton microcavities for analogue gravity, Bogoliubov dispersion mapping, and first-order dissipative phase transitions; (3) Nanophotonics — coupling single quantum emitters (nanofiber-coupled atoms, perovskite nanocrystals) for quantum photonics and sensing; displacement sensor based on optical nanofiber; (4) Optical computing interfaces with quantum systems. Marie Curie IOF Fellow (2011), City of Paris Young Scientist Award (2015).

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.
