Exciton-polaritons quantum fluid.
Exciton-polaritons turn photons into an interacting quantum fluid. The Bramati group at LKB has developed several tools to study quantum hydrodynamics with light: from measuring the Bogoliubov dispersion to studying superfluidity, driven-dissipative criticality, analogue gravity and quantum information in a fluid of light.
