Abstract: A bstractWe consider the holographic candidate for the entanglement of purification EP, given by the minimal cross sectional area of an entanglement wedge EW. The EP is generally very complicated quantity to obtain in field… 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.

Abstract: Abstract Bulk quantum fields are often said to contribute to the generalized entropy $$ \frac{A}{4{G}_N}+{S}_{\mathrm{bulk}} $$ A 4 G N + S bulk only at O(1). Nonetheless, in the context of evaporating black holes, O(1/GN… 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.
