Deep learning and the AdS/CFT correspondence [PDF]
Physical Review D, 2018 We present a deep neural network representation of the $\mathrm{AdS}/\mathrm{CFT}$ correspondence, and demonstrate the emergence of the bulk metric function via the learning process for given data sets of response in boundary quantum field theories.

Photon sphere and quasinormal modes in AdS/CFT
Journal of High Energy Physics, 2023 Photon spheres are the characteristic of general black holes, thus are a suitable touchstone for the emergence of gravitational spacetime in the AdS/CFT correspondence.

Supersymmetric gauge theories and the AdS / CFT correspondence [PDF]
, 2002 In these lecture notes we first assemble the basic ingredients of supersymmetric gauge theories (particularly N=4 super-Yang-Mills theory), supergravity, and superstring theory. Brane solutions are surveyed.

The AdS / CFT correspondence and a new positive energy conjecture for general relativity [PDF]
, 1998 We examine the AdS-CFT correspondence when gauge theory is considered on a compactified space with supersymmetry-breaking boundary conditions. We find that the corresponding supergravity solution has a negative energy, in agreement with the expected ...

AdS/CFT correspondence as a deep Boltzmann machine [PDF]
Physical Review D, 2019 We provide a deep Boltzmann machine (DBM) for the AdS/CFT correspondence. Under the philosophy that the bulk spacetime is a neural network, we give a dictionary between those, and obtain a restricted DBM as a discretized bulk scalar field theory in ...

Two-Boundaries AdS/CFT Correspondence in Dilatonic Gravity [PDF]
, 1998 We discuss dilatonic gravity (bulk theory) from the point of view of (generalized) AdS/CFT correspondence. Self-consistent dilatonic background is considered.

A new AdS/CFT correspondence [PDF]
Journal of High Energy Physics, 2000 We consider a geometric zero-radius limit for strings on $AdS_5\times S^5$, where the anti-de Sitter hyperboloid becomes the projective lightcone. In this limit the fifth dimension becomes nondynamical, yielding a different "holographic" interpretation than the usual "bulk to boundary" one.

Spinors and the AdS/CFT correspondence [PDF]
Physics Letters B, 1998 We consider a free massive spinor field in Euclidean Anti-de Sitter space. The usual Dirac action in bulk is supplemented by a certain boundary term. The boundary conditions of the field are parametrized by a spinor on the boundary, subject to a projection. We calculate the dependence of the partition function on this boundary spinor. The result agrees

The extended ADS/CFT correspondence [PDF]
Brazilian Journal of Physics, 2005 The correspondence between conformal covariant fields in Minkowski's space-time and isometric fields in the five dimensional anti-deSitter space-time is extended to a six-dimensional bulk space and its regular sub-manifolds, so as to include the analysis of evaporating Schwarzschild's black holes without loss of quantum unitarity.

Gravitational quasinormal modes for Anti-de Sitter black holes [PDF]
, 2002 Quasinormal mode spectra for gravitational perturbations of black holes in four dimensional de Sitter and anti-de Sitter space are investigated. The anti-de Sitter case is relevant to the ADS-CFT correspondence in superstring theory.
