  Strongly coupled quantum fluids are found in different forms, including
ultracold Fermi gases or tiny droplets of extremely hot Quark-Gluon Plasma.
Although the systems differ in temperature by many orders of magnitude, they
exhibit a similar almost inviscid fluid dynamical behavior. In this work, we
summarize some of the recent theoretical developments toward better
understanding this property in cold Fermi gases at and near unitarity.
