Gravity/Fluid Correspondence and Its Application on Bulk Gravity with U(1) Gauge Field [PDF]

Advances in High Energy Physics, 2014
As the long wavelength limit of the AdS/CFT correspondence, the gravity/fluid correspondence has been shown to be a useful tool for extracting properties of the fluid on the boundary dual to the gravity in the bulk. In this paper, after briefly reviewing

The Markov gap in the presence of islands

Journal of High Energy Physics, 2023
The Markov gap [1], namely the difference between reflected entropy and mutual information, is explicitly computed in the defect extremal surface model, JT gravity, and the generic 2d extremal black holes, in vacuum states.

Emergent Sasaki-Einstein geometry and AdS/CFT

Nature Communications, 2022
It is an outstanding question in quantum gravity how to describe the emergence of classical spacetime geometry from a quantum state. Here, the authors propose a construction in the context of the gauge/gravity correspondence, producing the classical ...

Constructing AdS2 flow geometries

Journal of High Energy Physics, 2021
We consider two-dimensional geometries flowing away from an asymptotically AdS2 spacetime. Macroscopically, flow geometries and their thermodynamic properties are studied from the perspective of dilaton-gravity models.

Topology and Wilson lines: global aspects of the double copy

Journal of High Energy Physics, 2020
The Kerr-Schild double copy relates exact solutions of gauge and gravity theories. In all previous examples, the gravity solution is associated with an abelian-like gauge theory object, which linearises the Yang-Mills equations.

Small Schwarzschild de Sitter black holes, quantum extremal surfaces and islands

Journal of High Energy Physics, 2022
We study 4-dimensional Schwarzschild de Sitter black holes in the regime where the black hole mass is small compared with the de Sitter scale. Then the de Sitter temperature is very low compared with that of the black hole and we study the black hole ...

Holographic coarse-graining: correlators from the entanglement wedge and other reduced geometries

Journal of High Energy Physics, 2022
There is some tension between two well-known ideas in holography. On the one hand, subregion duality asserts that the reduced density matrix associated with a limited region of the boundary theory is dual to a correspondingly limited region in the bulk ...

Introduction to Holographic Superconductors [PDF]

, 2010
These lectures give an introduction to the theory of holographic superconductors. These are superconductors that have a dual gravitational description using gauge/gravity duality.

Real-time gravitational replicas: low dimensional examples

Journal of High Energy Physics, 2021
We continue the study of real-time replica wormholes initiated in [1]. Previously, we had discussed the general principles and had outlined a variational principle for obtaining stationary points of the real-time gravitational path integral.

Gauge/Gravity Duality and Some Applications [PDF]

, 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.
