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 ...

Non-relativistic M2-branes and the AdS/CFT correspondence
Journal of High Energy PhysicsA non-relativistic limit of the AdS/CFT correspondence is studied in the context of M2-branes. On the field theory side this corresponds to a near-BPS limit of ABJM that localises onto solutions of Hitchin’s equations.

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.

AdS/CFT correspondence with heat conduction [PDF]
Physics Letters B, 2007 We study an extension of the gravity dual to a perfect fluid model found by Janik and Peschanski. By relaxing one of the constraints, namely invariance under reflection in the longitudinal direction, we introduce a metric ansatz which includes off-diagonal terms. We also include an $R$-charge following Bak and Janik.

Supersymmetry in the AdS/CFT correspondence [PDF]
Physics Letters B, 1999 We study how local symmetry transformations of (p, q) anti de Sitter supergravities in three dimensions act on fields on the two-dimensional boundary. The boundary transformation laws are shown to be the same as those of two-dimensional (p, q) conformal supergravities for p, q \leq 2.

Scrambling-Enhanced Quantum Battery Charging in Black Hole Analogues. [PDF]
Adv Sci (Weinh)By employing a black‐hole‐analog quantum battery constructed from a position‐dependent XY model, its dynamical behavior is investigated through a quench of the scrambling parameter. It is systematically quantified that how the simulated scrambling improves key performance metrics‐namely, stored energy, peak power, and charging time‐thereby offering a ...

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 ...

Confinement and the AdS/CFT correspondence [PDF]
Physics Letters B, 2000 We study the thermodynamics of the confined and unconfined phases of superconformal Yang-Mills in finite volume and at large N using the AdS/CFT correspondence. We discuss the necessary conditions for a smooth phase crossover and obtain an N-dependent curve for the phase boundary.
