Foundational aspects of relativistic hydrodynamics

How small can a droplet be and still behave as a fluid? The latest research unexpectedly suggests that droplets of the size of a fraction of an atomic nucleus made from quark-gluon plasma, an exotic type of matter of extreme energy density, have liquid-like properties. Quarkgluon plasma once filled the entire universe and can today be recreated in high-energy collisions between atomic nuclei. This timely workshop will bring together a multi-disciplinary group of researchers to rethink the foundations behind our contemporary understanding of ultra-hot and fast-moving fluids.
