ABSTRACT
Scalar quantum fluids represent a unique type of fluid that can be described by a phase and amplitude. They have attracted a wide interest for their unique properties when set under rotation. Many experiments have been carried out on superfluid Helium 4 [82] and condensates of weakly interacting atoms set into rotation [87]. The main feature that is common to all kinds of scalar quantum fluids is that, after a given threshold value for the rotation velocity, proliferation of quantized vortices takes place [111].
