Phase diagram of one-dimensional driven-dissipative exciton-polariton condensates
Francesco Vercesi, Quentin Fontaine, Sylvain Ravets +4
We consider a one-dimensional driven-dissipative exciton-polariton condensate under incoherent pump, described by the stochastic generalized Gross-Pitaevskii equation. It was shown…
Observation of KPZ universal scaling in a one-dimensional polariton condensate
Quentin Fontaine, Davide Squizzato, Florent Baboux +14
Revealing universal behaviors is a hallmark of statistical physics. Phenomena such as the stochastic growth of crystalline surfaces, of interfaces in bacterial colonies, and spin t…
Dissipation-enhanced collapse singularity of a nonlocal fluid of light in a hot atomic vapor
Pierre Azam, Adrien Fusaro, Quentin Fontaine +6
We study the out-of-equilibrium dynamics of a two-dimensional paraxial fluid of light using a near-resonant laser propagating through a hot atomic vapor. We observe a double shock-…
Quantitative Analysis of Shock Wave Dynamics in a Fluid of Light
T. Bienaimé, M. Isoard, Q. Fontaine +4
We report on the formation of a dispersive shock wave in a nonlinear optical medium. We monitor the evolution of the shock by tuning the incoming beam power. The experimental obser…
Paraxial fluid of light in hot atomic vapors
Quentin Fontaine
Quantum fluids of light are the photonic counterpart of Bose gases. They currently attract increasing interest since they are versatile and highly tunable systems for probing many-…
Interferences between Bogoliubov excitations and their impact on the evidence of superfluidity in a paraxial fluid of light
Quentin Fontaine, Pierre-Elie Larré, Giovanni Lerario +7
Paraxial fluids of light represent an alternative platform to atomic Bose-Einstein condensates and superfluid liquids for the study of the quantum behaviour of collective excitatio…
Compensation of Beer-Lambert attenuation using non-diffracting Bessel beams
Quentin Fontaine, Huiqin Hu, Simon Pigeon +5
We report on a versatile method to compensate the linear attenuation in a medium, independently of its microscopic origin. The method exploits diffraction-limited Bessel beams and…
Observation of the Bogoliubov dispersion relation in a fluid of light
Q. Fontaine, T. Bienaimé, S. Pigeon +3
Quantum fluids of light are photonic counterpart to atomic Bose gases and are attracting increasing interest for probing many-body physics quantum phenomena such as superfluidity.…
