Characterizing far-from-equilibrium dynamics in quantum many-body systems is crucial for demystifying fundamental physical phenomena such as the mechanism of thermalization in isolated many-body systems and the quantum nature of black hole formation and evaporation. Entanglement has proven to be an illuminating tool for classifying such complex physics. In this talk, I will present universal descriptions of entanglement dynamics in integrable and chaotic quantum systems. While the former can be described by an effective description of quasi-particles, the latter must be described by a non-local membrane-like object. I will show that these frameworks accurately account for fine-grained entanglement measures such as mutual information, logarithmic negativity, and reflected entropy for a wide range of systems including random unitary circuits, conformal field theories, and spin chains.
