Quantum entanglement in condensed matter systems

N Laflorencie - Physics Reports, 2016‏ - Elsevier
This review focuses on the field of quantum entanglement applied to condensed matter
physics systems with strong correlations, a domain which has rapidly grown over the last …

Entanglement entropy of black holes

SN Solodukhin - Living Reviews in Relativity, 2011‏ - Springer
The entanglement entropy is a fundamental quantity, which characterizes the correlations
between sub-systems in a larger quantum-mechanical system. For two sub-systems …

Towards a derivation of holographic entanglement entropy

H Casini, M Huerta, RC Myers - Journal of High Energy Physics, 2011‏ - Springer
We provide a derivation of holographic entanglement entropy for spherical entangling
surfaces. Our construction relies on conformally map** the boundary CFT to a hyperbolic …

Why does quantum field theory in curved spacetime make sense? And what happens to the algebra of observables in the thermodynamic limit?

E Witten - Dialogues Between Physics and Mathematics: CN …, 2022‏ - Springer
This article aims to explain some of the basic facts about the questions raised in the title,
without the technical details that are available in the literature. We provide a gentle …

Holographic c-theorems in arbitrary dimensions

RC Myers, A Sinha - Journal of High Energy Physics, 2011‏ - Springer
We re-examine holographic versions of the c-theorem and entanglement entropy in the
context of higher curvature gravity and the AdS/CFT correspondence. We select the gravity …

Renormalization group running of the entanglement entropy of a circle

H Casini, M Huerta - Physical Review D—Particles, Fields, Gravitation, and …, 2012‏ - APS
We show, using strong subadditivity and Lorentz covariance, that in three-dimensional
space-time the entanglement entropy of a circle is a concave function. This implies the …

Holographic calculations of Renyi entropy

LY Hung, RC Myers, M Smolkin, A Yale - Journal of High Energy Physics, 2011‏ - Springer
A bstract We extend the approach of [12] to a new calculation of the Rényi entropy of a
general CFT in d dimensions with a spherical entangling surface, in terms of certain thermal …

Entanglement entropy from a holographic viewpoint

T Takayanagi - Classical and Quantum Gravity, 2012‏ - iopscience.iop.org
The entanglement entropy has been historically studied by many authors in order to obtain
quantum mechanical interpretations of the gravitational entropy. The discovery of anti-de …

CFT in AdS and boundary RG flows

S Giombi, H Khanchandani - Journal of High Energy Physics, 2020‏ - Springer
A bstract Using the fact that flat space with a boundary is related by a Weyl transformation to
anti-de Sitter (AdS) space, one may study observables in boundary conformal field theory …

Entanglement entropy in de Sitter space

J Maldacena, GL Pimentel - Journal of High Energy Physics, 2013‏ - Springer
A bstract We compute the entanglement entropy for some quantum field theories on de Sitter
space. We consider a superhorizon size spherical surface that divides the spatial slice into …
