Contribution title: Experimental evidences of light superfluidity in a nonlinear crystal

Quantum fluids of light merge many-body physics and nonlinear optics, revealing quantum hydrodynamics features of light when it propagates in a nonlinear media. The ability of light to behave as a superfluid is one example of these features. Here, we present a direct experimental detection of the frictional-superfluid transition in the flow of a fluid of light past a weakly perturbing localized obstacle in a bulk nonlinear crystal. The flexibility of the experimental apparatus for shaping both the flow and the potential landscape paves the way for the simulation of quantum phase transitions in complex systems.
