Journal ArticleDOI

Spectrum of End of the World Branes in Holographic BCFTs

Masamichi Miyaji, +4 more
- 11 Mar 2021 - 
TL;DR: In this paper, the authors studied overlaps between two regularized boundary states in conformal field theories and showed that such overlaps are exponentially suppressed as the energy of open strings connecting two different boundaries is exponentially suppressed.
Journal ArticleDOI

Towards an entanglement measure for mixed states in CFTs based on relative entropy

Tadashi Takayanagi, +3 more
- 25 Jul 2018 - 
TL;DR: In this article, the relative entropy of entanglement (REE) measure of bipartite mixed states is defined by the minimum of the relative entangement S(ρAB ||σAB ) between a given mixed state ρAB and an arbitrary separable state σAB.
Journal ArticleDOI

Aspects of pseudoentropy in field theories

Ali Mollabashi, +7 more
TL;DR: In this paper, the authors explore properties of pseudoentropy in quantum field theories and spin systems from several approaches, including the area-law behavior, saturation behavior, and non-positivity of difference between the pseudo entropy and averaged entanglement entropy in the same quantum phase.
Journal ArticleDOI

AdS Bubbles, Entropy and Closed String Tachyons

Tatsuma Nishioka, +1 more
- 03 Nov 2006 - 
TL;DR: In this article, the authors studied the connection between AdS bubbles (AdS solitons) and closed string tachyon condensations and showed that the entanglement entropy decreases under the condensation.
Journal ArticleDOI

Double-trace deformations and entanglement entropy in AdS

Taiki Miyagawa, +3 more
- 01 Jan 2016 - 
TL;DR: In this paper, the authors compute the bulk entanglement entropy of a massive scalar field in a Poincare AdS with the Dirichlet and Neumann boundary condition when they trace out a half space.
