DOI: 10.1007/jhep06(2024)151
Abstract: It has been shown in recent works that JT gravity with matter with two boundaries has a type II∞ algebra on each side. As the bulk spacetime between the two boundaries fluctuates in quantum nature,… read more here.

Abstract: The concept of the generalized entanglement wedge was recently proposed by Bousso and Penington, which states that any bulk gravitational region a possesses an associated generalized entanglement wedge E(a) ⊃ a on a static Cauchy… read more here.

Abstract: When absorbing boundary conditions are used to evaporate a black hole in AdS/CFT, we show that there is a phase transition in the location of the quantum Ryu-Takayanagi surface, at precisely the Page time. The… read more here.

DOI: 10.1103/physrevd.100.126006
Abstract: We show that the bulk region reconstructable from a given boundary subregion --- which we term the reconstruction wedge --- can be much smaller than the entanglement wedge even when backreaction is small. We find… read more here.
