Journal ArticleDOI
Quantum entanglement of local operators in conformal field theories.
TL;DR: A series of quantities which characterize a given local operator in any conformal field theory from the viewpoint of quantum entanglement are introduced, defined by the increased amount of (Rényi)Entanglement entropy at late time for an excited state defined by acting the local operator on the vacuum.
Journal ArticleDOI
AdS/CFT and strong subadditivity of entanglement entropy
TL;DR: In this paper, the strong subadditivity property of the entanglement entropy in conformal field theories has been verified via direct calculations using annuli or cusps and the Bousso bound.
Journal ArticleDOI
Continuous Multiscale Entanglement Renormalization Ansatz as Holographic Surface-State Correspondence
Masamichi Miyaji,Tokiro Numasawa,Noburo Shiba,Tadashi Takayanagi,Tadashi Takayanagi,Kento Watanabe +5 more
TL;DR: The surface-state correspondence works in the setup of AdS(3)/CFT(2) by generalizing the formulation of a continuous multiscale entanglement renormalization group ansatz by giving an identification of bulk local operators which reproduces correct scalar field solutions on AdS (3) and bulk scalar propagators.
Journal ArticleDOI
Brane-Antibrane Action from Boundary String Field Theory
TL;DR: In this article, the boundary string field theory description of brane-antibrane systems is given, and the tachyon potential and the Tachyon condensation are discussed exactly.
Journal ArticleDOI
Surface/State Correspondence as a Generalized Holography
TL;DR: In this article, a new duality relation between codimension two space-like surfaces in gravitational theories and quantum states in dual Hilbert spaces was proposed, which largely generalizes the idea of holography such that we do not need to rely on any existence of boundaries in gravitational spacetimes.
