Misha Usatyuk (UCB) “Quantum Maximin Surfaces” *ZOOM meeting ID 370 438 207* “BCTP String seminar”
–
In AdS/CFT the Engelhardt-Wall prescription states that the entanglement entropy of a boundary subregion is given by the generalized entropy of a minimal quantum extremal surface. Since quantum extremal surfaces are not constrained to one time slice proving certain consistency conditions such as strong subadditivity has remained an open problem. We formulate a quantum generalization of maximin surfaces and show … Read More
