Holographic codes from hyperinvariant tensor networks [PDF]

open access: yesNature Communications, 2023
Holographic quantum-error correcting codes are models of bulk/boundary dualities such as the anti-de Sitter/conformal field theory (AdS/CFT) correspondence, where a higher-dimensional bulk geometry is associated with the code’s logical degrees of freedom.

Tensor network and (p-adic) AdS/CFT

open access: yesJournal of High Energy Physics, 2018
We use the tensor network living on the Bruhat-Tits tree to give a concrete realization of the recently proposed p-adic AdS/CFT correspondence (a holographic duality based on the p-adic number field ℚ p ).

Holographic Duality with a View Toward Many-Body Physics [PDF]

open access: yesAdvances in High Energy Physics, 2010
These are notes based on a series of lectures given at the KITP workshop Quantum Criticality and the AdS/CFT Correspondence in July, 2009. The goal of the lectures was to introduce condensed matter physicists to the AdS/CFT correspondence.

Some Implications of Perturbative Approach to AdS/CFT Correspondence [PDF]

open access: green, 2007
We show some implications of the approach to AdS/CFT correspondence based on Type IIB string in the flat space-time with D3-branes proposed in our previous paper.

Holographic quantum error-correcting codes: toy models for the bulk/boundary correspondence [PDF]

open access: yesJournal of High Energy Physics, 2015
We propose a family of exactly solvable toy models for the AdS/CFT correspondence based on a novel construction of quantum error-correcting codes with a tensor network structure.

Discrete gravity on random tensor network and holographic Rényi entropy

open access: yesJournal of High Energy Physics, 2017
In this paper we apply the discrete gravity and Regge calculus to tensor networks and Anti-de Sitter/conformal field theory (AdS/CFT) correspondence. We construct the boundary many-body quantum state |Ψ〉 using random tensor networks as the holographic ...

Holographic duality between local Hamiltonians from random tensor networks

open access: yesJournal of High Energy Physics, 2022
The AdS/CFT correspondence realises the holographic principle where information in the bulk of a space is encoded at its border. We are yet a long way from a full mathematical construction of AdS/CFT, but toy models in the form of holographic quantum ...

Tensor network models of AdS/qCFT [PDF]

open access: yesQuantum, 2022
The study of critical quantum many-body systems through conformal field theory (CFT) is one of the pillars of modern quantum physics. Certain CFTs are also understood to be dual to higher-dimensional theories of gravity via the anti-de Sitter/conformal ...

Universal entropy and hawking radiation of near-extremal AdS4 black holes

open access: yesJournal of High Energy Physics, 2021
We compute the Bekenstein-Hawking entropy of near-extremal asymptotically AdS4 electrically charged rotating black holes using three different methods: (i) from the gravity solution, (ii) from the near-horizon Kerr/CFT correspondence and (iii) from the ...

Asymptotically free AdS3/CFT2

open access: yesJournal of High Energy Physics, 2022
We propose a new AdS 3 /CFT 2 duality, in which the bulk string theory has a target spacetime AdS 3 times a squashed three-sphere S ♭ 3 $$ {\mathbbm{S}}_{\flat}^3 $$ , and the dual CFT 2 is a symmetric product of sigma models on ℝ ϕ × S ♭ 3 $$ {\mathbbm ...
