What is a perfect fluid? It is a theoretical model of a fluid that allows us to assume that the fluid is not viscous, that it does not conduct heat, that it is incompressible and does not create vortices. It is therefore an approximation of reality that simplifies theoretical predictions of fluid flows. For the first time, an international team has experimentally demonstrated this same behaviour for light immersed in a medium of low refractive index.
