The flow of light is a fascinating playground for new physics and table-top studies of superfluidity, condensation, vorticity, turbulence and synthetic gauge field effects, just to name a few. Traditionally this field has been dominated by studies in polariton fluids but there other relevant systems are gaining ground such as, for example, what we may call “propagating” fluids of light. This workshop will be an opprotunity to discuss the latest developments in the field, bringing together ideas from laser physics, fluids of light, hydrodynamics, analogue gravity and artifical gauge fields.
