Explore correlation functions in hydrodynamics beyond the Boltzmann-Gibbs paradigm in this 27-minute conference talk by Benjamin Doyon at the Kavli Institute for Theoretical Physics. Delve into topics such as the XX model, hyperbolic scaling, integrable models, and twist fields as part of the 2021 Non-Equilibrium Universality in Many-Body Physics KITP Conference. Gain insights into the intersection of statistical physics, AMO, condensed matter, and high-energy physics, focusing on novel phases of matter far from equilibrium and their associated universality classes. Discover how quantum simulators have sparked dialogue between diverse scientific fields and learn about the potential for experiments to enhance our understanding of far-from-equilibrium universality.
