Black holes (often) saturate entanglement entropy the fastest
There is a simple bound on how fast the entanglement entropy of a subregion of a many-body quantum system can saturate in a quench: tsat≥R/vB, where tsat is the saturation time, R the radius of the largest inscribed sphere, and vB the butterfly velocity characterizing operator growth. By combining a...
