Discrete gravity on random tensor network and holographic Rényi entropy
Journal 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 ...

Ads/CFT correspondence and symmetry breaking [PDF]
Nuclear Physics B, 1999 We study, using the dual AdS description, the vacua of field theories where some of the gauge symmetry is broken by expectation values of scalar fields. In such vacua, operators built out of the scalar fields acquire expectation values, and we show how to calculate them from the behavior of perturbations to the AdS background near the boundary ...

Some Aspects of the AdS/CFT Correspondence [PDF]
, 2004 This is a very brief review of some aspects of the AdS/CFT correspondence with an emphasis on the role of the topology of the boundary and the meaning of the sum over bulk geometries.

Finite-N superconformal index via the AdS/CFT correspondence [PDF]
, 2021 We propose a prescription to calculate the superconformal index of the ${\cal N}=4$ $U(N)$ supersymmetric Yang-Mills theory with finite $N$ on the AdS side. The finite $N$ corrections are included as contributions of D3-branes wrapped around three-cycles

Quantization in AdS and the AdS/CFT Correspondence [PDF]
International Journal of Modern Physics A, 2003 The quantization of a scalar field in Ads leads to two kinds of normalizable modes, usually called regular and irregular modes. The regular one is easily taken into account in the standard prescription for the AdS/CFT correspondence. The irregular mode requires a modified prescription which argue is not completely satisfactory.

Simple Bulk Reconstruction in AdS/CFT Correspondence [PDF]
Progress of Theoretical and Experimental Physics, 2021 In this paper, we show that the bulk reconstruction in the AdS/CFT correspondence is rather simple and has an intuitive picture, by showing that the HKLL bulk reconstruction formula can be simplified.

Superfluidity in the AdS/CFT correspondence [PDF]
Journal of High Energy Physics, 2001 A chemical potential may be introduced into the AdS/CFT correspondence by setting the D3 branes of the construction spinning. In the field theory the fermionic modes are expected to condense as Cooper pairs, although at zero temperature the chemical potential destabilizes the scalar sector of the N=4 theory obscuring this phenomena.

Holographic duality between local Hamiltonians from random tensor networks
Journal 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]
Quantum, 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 ...
