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

open access: yesAdvances 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

Emergent Sasaki-Einstein geometry and AdS/CFT

open access: yesNature 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

open access: yesJournal 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.

The Markov gap in the presence of islands

open access: yesJournal 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.

Topology and Wilson lines: global aspects of the double copy

open access: yesJournal 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.

Purification complexity without purifications

open access: yesJournal of High Energy Physics, 2021
We generalize the Fubini-Study method for pure-state complexity to generic quantum states by taking Bures metric or quantum Fisher information metric (QFIM) on the space of density matrices as the complexity measure.

Dynamical fixed points in holography

open access: yesJournal of High Energy Physics, 2022
Typically, an interactive system evolves towards thermal equilibrium, with hydrodynamics representing a universal framework for its late-time dynamics.

Differential Geometrical Formulation of Gauge Theory of Gravity [PDF]

open access: yes, 2002
Differential geometric formulation of quantum gauge theory of gravity is studied in this paper. The quantum gauge theory of gravity which is proposed in the references hep-th/0109145 and hep-th/0112062 is formulated completely in the framework of ...

Sewing spacetime with Lorentzian threads: complexity and the emergence of time in quantum gravity

open access: yesJournal of High Energy Physics, 2022
Holographic entanglement entropy was recently recast in terms of Riemannian flows or ‘bit threads’. We consider the Lorentzian analog to reformulate the ‘complexity=volume’ conjecture using Lorentzian flows — timelike vector fields whose minimum flux ...

Introduction to Holographic Superconductors [PDF]

open access: yes, 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.
