Entanglement Entropies of Equilibrated Pure States in Quantum Many-Body Systems and Gravity
Hong Liu, Shreya Vardhan
Abstract
A universal approximation for the Renyi entropies of equilibrated pure states is presented, helping to understand how the process of thermalization is consistent with unitarity in quantum chaotic systems and models of evaporating black holes.
