Our letter about the observation of a diffusive Nambu–Goldstone mode. Although these modes are known to propagate as sound waves in conservative systems, non-equilibrium phase transitions have been predicted to feature a diffusive Nambu–Goldstone mode and we observed this in a quantum fluid of light.

A letter about the observation of the famous Jones-Roberts solitons in a quantum fluid of light. These solitons were predicted in 1981 and never observed before. It's an editor's suggestion in Physical Review Letters !

A paper about the first realization of a binary fluid of light. We show how to create a Bose-Bose mixture of photons and we explore the spin and density modes of this new system.

A (long) review paper about the physics of paraxial fluids of light. It goes from the theoretical framework to the experimental realizations. It also discusses the experimental techniques and the outlook of the field.

A general review to discuss all the cool physics done with hot atomic vapors. It goes from conventional non-linear wave-mixing to squeezing, quantum memories and more recent topics about quantum fluids of light.

Fluids of light in the paraxial geometry are intrinsically out-of-equilibrium. We explore the role of the interaction quench on the structure factor of our fluid and we make connection with cosmological particle creation.

A promising spectroscopy technique to measure the dispersion relation of a Polariton Quantum Fluid even at very low momenta, and with access to the ghost (negative energy) modes.

We excite a quantum fluids of light with a bit of kinetic energy (associated to a temperature) and we study the quasi long range order (algebraic coherence) to explore phase transition in non-equilibrium state in collaboration with Nicolas Cherroret.

Fluids of light in the propagating geometry is quite a new field. A lot of common techniques of cold atoms are missing. We found a way to perform Bragg-like spectroscopy and measure the structure factor in a fluid of light.

Our first paper about fluids of light in the propagating geometry. We took quantum fluids of light analogy seriously and we realized that they are actually superfluids ! The beginning of a long journey...
