"Under appropriate conditions, light propagating in nonlinear media exhibitsa remarkable behaviour - the propagation is identical to that of a fluid.Perturbations on the transverse beam profile will propagate as waves in aperfect fluid and in many cases the fluid behaves as a superfluid that can beused to study turbulence, vorticity and other phenomena that are of relevance for superfluids and Bose-Einstein condensates. This project, at theinterface between laser physics, superfluid physics and quantum physics willinvestigate new systems in which to observe photon fluid dynamics and willthen apply these concepts to a variety of problems. Most notably, we have along-standing interest in so-called ""analogue gravity"", i.e. the creation ofhydrodynamical analogues for curved spacetimes that can then be used tomimic and study objects such as (artificial) rotating black holes or (artificial)gravitational waves. This project is strictly experimental"
