Description
Criticality in QCD manifests itself in two complementary ways: through enhanced fluctuations and through modifications of the macroscopic evolution of the medium. While fluctuation observables have long been regarded as key signatures of the QCD critical point, the hydrodynamic response of QCD matter to criticality may provide equally important information. I will discuss recent progress in understanding hydrodynamic evolution near the QCD critical point, with particular emphasis on the focusing of hydrodynamic trajectories and its implications for heavy-ion collision phenomenology.
