Experiments have shown that both the Quark-Gluon Plasma as well as ultra-cold Fermi gases near unitarity are nearly perfect fluids. This means that the ratio of shear viscosity to entropy density is very small, and that kinetic theory and quasi-particle descriptions are not expected to be reliable. In order to fully quantify these statements we need to understand hydrodynamic models in a new physical regime of large velocity gradients, large fluctuations, and small physical volumes. We plan to bring together experts from high energy nuclear physics, string theory and atomic physics to advance our understanding of strongly coupled fluids, and to address such issues as the role of fluctuations, pre-equilibrium matching, the applicability of hydrodynamics in very small systems like pp and pA collisions, and the applicability of the AdS/CFT correspondence. We also plan to address the possibility of observing new hydrodynamic effects related to anomalies.
