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-…
Analogue cosmological particle creation in an ultracold quantum fluid of light
Jeff Steinhauer, Murad Abuzarli, Tangui Aladjidi +6
In inflationary cosmology, the rapid expansion of the early universe resulted in the spontaneous production of cosmological particles from vacuum fluctuations, observable today in…
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…
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…
Observation of a Spinning Top in a Bose-Einstein Condensate
R. N. Bisset, S. Serafini, E. Iseni +5
Boundaries strongly affect the behavior of quantized vortices in Bose-Einstein condensates, a phenomenon particularly evident in elongated cigar-shaped traps where vortices tend to…
Vortex reconnections and rebounds in trapped atomic Bose--Einstein condensates
Simone Serafini, Luca Galantucci, Elena Iseni +6
Reconnections and interactions of filamentary coherent structures play a fundamental role in the dynamics of fluids, plasmas and nematic liquid crystals. In fluids, vortex reconnec…
Spin-Dipole Oscillation and Polarizability of a Binary Bose-Einstein Condensate near the Miscible-Immiscible Phase Transition
Tom Bienaimé, Eleonora Fava, Giacomo Colzi +6
We report on the measurement of the spin-dipole (SD) polarizability and of the frequency of the SD oscillation of a two-component Bose-Einstein condensate of sodium atoms occupying…
Creation and counting of defects in a temperature quenched Bose-Einstein Condensate
Simone Donadello, Simone Serafini, Tom Bienaimé +3
We study the spontaneous formation of defects in the order parameter of a trapped ultracold bosonic gas while crossing the critical temperature for Bose-Einstein Condensation (BEC)…
