Critical reflections on asymptotically safe gravity

A Bonanno, A Eichhorn, H Gies, JM Pawlowski… - Frontiers in …, 2020‏ - frontiersin.org
Asymptotic safety is a theoretical proposal for the ultraviolet completion of quantum field
theories, in particular for quantum gravity. Significant progress on this program has led to a …

Entanglement entropy: holography and renormalization group

T Nishioka - Reviews of Modern Physics, 2018‏ - APS
Entanglement entropy plays a variety of roles in quantum field theory, including the
connections between quantum states and gravitation through the holographic principle. This …

Generalized entropy for general subregions in quantum gravity

K Jensen, J Sorce, AJ Speranza - Journal of High Energy Physics, 2023‏ - Springer
A bstract We consider quantum algebras of observables associated with subregions in
theories of Einstein gravity coupled to matter in the GN→ 0 limit. When the subregion is …

The Ryu–Takayanagi formula from quantum error correction

D Harlow - Communications in Mathematical Physics, 2017‏ - Springer
I argue that a version of the quantum-corrected Ryu–Takayanagi formula holds in any
quantum error-correcting code. I present this result as a series of theorems of increasing …

Quantum corrections to holographic entanglement entropy

T Faulkner, A Lewkowycz, J Maldacena - Journal of High Energy Physics, 2013‏ - Springer
A bstract We consider entanglement entropy in quantum field theories with a gravity dual. In
the gravity description, the leading order contribution comes from the area of a minimal …

Quantum focusing conjecture

R Bousso, Z Fisher, S Leichenauer, AC Wall - Physical Review D, 2016‏ - APS
We propose a universal inequality that unifies the Bousso bound with the classical focusing
theorem. Given a surface σ that need not lie on a horizon, we define a finite generalized …

Entanglement equilibrium and the Einstein equation

T Jacobson - Physical review letters, 2016‏ - APS
A link between the semiclassical Einstein equation and a maximal vacuum entanglement
hypothesis is established. The hypothesis asserts that entanglement entropy in small …

Local subsystems in gauge theory and gravity

W Donnelly, L Freidel - Journal of High Energy Physics, 2016‏ - Springer
A bstract We consider the problem of defining localized subsystems in gauge theory and
gravity. Such systems are associated to spacelike hypersurfaces with boundaries and …

TASI Lectures on the Emergence of the Bulk in AdS/CFT

D Harlow - arxiv preprint arxiv:1802.01040, 2018‏ - arxiv.org
These lectures review recent developments in our understanding of the emergence of local
bulk physics in AdS/CFT. The primary topics are sufficient conditions for a conformal field …

Remarks on entanglement entropy for gauge fields

H Casini, M Huerta, JA Rosabal - Physical Review D, 2014‏ - APS
In gauge theories the presence of constraints can obstruct expressing the global Hilbert
space as a tensor product of the Hilbert spaces corresponding to degrees of freedom …
