“…7,8 This means that the analogue fluid of light is two-dimensional, and each slice along the propagation direction represents the fluid of light at different moments in time. Over the past years, many experimental efforts have observed a range of quantum-like effects with these paraxial configurations, including superfluidity of light, 1,17 Bogoliubov dispersion relation measurements, 18,19 vortex turbulence, 1, 4, 20 analogue cosmological particle creation, 21 or superradiance-like signatures, 22 to name a few. Usually, these experimental implementations use hot atomic vapors, 23 thermo-optical media, 24,25 or photorefractive crystals 1, 3 as the nonlinear optical material.…”
