Time-independence of gravitational Rényi entropies and unitarity in quantum gravity

open access: yesJournal of High Energy Physics, 2021
The Hubeny-Rangamani-Takayanagi surface γ HRT computing the entropy S(D) of a domain of dependence D on an asymptotically AdS boundary is known to be causally inaccessible from D. We generalize this gravitational result to higher replica numbers n > 1 by

The Markov gap for geometric reflected entropy

open access: yesJournal of High Energy Physics, 2021
The reflected entropy S R (A : B) of a density matrix ρ AB is a bipartite correlation measure lower-bounded by the quantum mutual information I(A : B). In holographic states satisfying the quantum extremal surface formula, where the reflected entropy is ...

Gauge/Gravity Duality and Some Applications [PDF]

open access: yes, 2010
We discuss the AdS/CFT correspondence in which space-time emerges from an interacting theory of D-branes and open strings. These ideas have a historical continuity with QCD which is an interacting theory of quarks and gluons.

Symmetry-resolved entanglement in AdS3/CFT2 coupled to U(1) Chern-Simons theory

open access: yesJournal of High Energy Physics, 2021
We consider symmetry-resolved entanglement entropy in AdS3/CFT2 coupled to U(1) Chern-Simons theory. We identify the holographic dual of the charged moments in the two-dimensional conformal field theory as a charged Wilson line in the bulk of AdS3 ...

Complexity and Multi-boundary Wormholes in 2 + 1 dimensions

open access: yesJournal of High Energy Physics, 2023
Three dimensional wormholes are global solutions of Einstein-Hilbert action. These space-times which are quotients of a part of global AdS3 have multiple asymptotic regions, each with conformal boundary S 1 × ℝ, and separated from each other by horizons.

Spectroscopy of fermionic operators in AdS/CFT [PDF]

open access: yes, 2006
We compute the spectrum of color-singlet fermionic operators in the N=2 gauge theory on intersecting D3 and D7-branes using the AdS/CFT correspondence.

Direct test of the gauge-gravity correspondence for Matrix theory correlation functions [PDF]

open access: yesJournal of High Energy Physics, 2011
We study correlation functions in (0+1)-dimensional maximally supersymmetric U(N) Yang-Mills theory, which was proposed by Banks et al. as a non-perturbative definition of 11-dimensional M-theory in the infinite-momentum frame. We perform first-principle calculations using Monte Carlo simulations, and compare the results against the predictions ...

Holographic Fermi and Non-Fermi Liquids with Transitions in Dilaton Gravity [PDF]

open access: yes, 2011
We study the two-point function for fermionic operators in a class of strongly coupled systems using the gauge-gravity correspondence. The gravity description includes a gauge field and a dilaton which determines the gauge coupling and the potential ...

Can one hear the shape of a wormhole?

open access: yesJournal of High Energy Physics, 2022
A large class of flat big bang-big crunch cosmologies with negative cosmological constant are related by analytic continuation to asymptotically AdS traversable wormholes with planar cross section.

One-loop universality of holographic codes

open access: yesJournal of High Energy Physics, 2020
Recent work showed holographic error correcting codes to have simple universal features at O(1/G). In particular, states of fixed Ryu-Takayanagi (RT) area in such codes are associated with flat entanglement spectra indicating maximal entanglement between
