Tomorrow Jinzhao will tell us about "The refined quantum extremal surface prescription from the asymptotic equipartition property". See below for the abstract. Usual time and place: 2pm https://ethz.zoom.us/j/362994444.

Best,

The quantum extremal surface prescription, born out of the Ryu Takayanagi formula in AdS/CFT, is a general rule of computing entanglement entropy in gravity. Its usefulness is highlighted in the recent black hole Page curve calculation.  In this talk I will introduce the recent refinement of the QES prescription, showing the significance of the smooth conditional min/max-entropies. Inspired by the asymptotic equipartition property, I will sketch a path integral derivation of it in the context of holography with a novel replica trick. In the end, I will show that the derivation implies the correction also applies beyond AdS/CFT and in particular to the Page curve.
