Swimming against a superfluid flow: Self-propulsion via vortex-antivortex shedding in a quantum fluid of light
Myrann Baker-Rasooli, Tangui Aladjidi, Tiago D. Ferreira +4
A superfluid flows without friction below a critical velocity, exhibiting zero drag force on impurities. Above this threshold, superfluidity breaks down, and the internal energy is…
Measuring the group velocity dispersion in near resonant hot atomic vapors
Alix Merolle, Quentin Glorieux
Group velocity dispersion (GVD) in near-resonant hot atomic vapors is difficult to measure with standard pulse broadening or interferometric techniques, as absorption, pulse distor…
Vortex leapfrogging and superfluid dissipation mechanisms in a fluid of light
Myrann Baker-Rasooli, Nathan du Toit, Nicolas Pavloff +1
We report the experimental observation of vortex leapfrogging in a two-dimensional fluid of light. By imprinting two vortex-antivortex pairs and tracking their real-time evolution…
Machine learning approach to single-shot multiparameter estimation for the non-linear Schrödinger equation
Louis Rossignol, Tangui Aladjidi, Myrann Baker-Rasooli +1
The nonlinear Schrödinger equation (NLSE) is a fundamental model for wave dynamics in nonlinear media ranging from optical fibers to Bose-Einstein condensates. Accurately estimati…
Paraxial fluids of light
Quentin Glorieux, Clara Piekarski, Quentin Schibler +2
Paraxial fluids of light are a promising platform for exploring collective phenomena in a highly tunable environment. These systems, which map the propagation of light through nonl…
Observation of Jones-Roberts solitons in a paraxial quantum fluid of light
Myrann Baker-Rasooli, Tangui Aladjidi, Nils A. Krause +2
We investigate the formation and dynamics of Jones-Roberts solitons in a smoothly inhomogeneous quantum fluid. To do so, we create a superfluid of light using paraxial, near-resona…
