We review the holographic correspondence between field theories and string/M theory,
focusing on the relation between compactifications of string/M theory on Anti-de Sitter …

In this report we review the microscopic formulation of the five-dimensional black hole of
type IIB string theory in terms of the D1–D5 brane system. The emphasis here is more on the …

A holographic derivation of the entanglement entropy in quantum (conformal) field theories
is proposed from anti–de Sitter/conformal field theory (AdS/CFT) correspondence. We argue …

General relativity contains solutions in which two distant black holes are connected through
the interior via a wormhole, or Einstein‐Rosen bridge. These solutions can be interpreted as …

A bstract We consider classical Euclidean gravity solutions with a boundary. The boundary
contains a non-contractible circle. These solutions can be interpreted as computing the trace …

This is an extended version of our short report [1], where a holographic interpretation of
entanglement entropy in conformal field theories is proposed from AdS/CFT …

We propose a dual non-perturbative description for maximally extended Schwarzschild Anti-
de-Sitter spacetimes. The description involves two copies of the conformal field theory …

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 …

A bstract We compute the time-dependent entanglement entropy of a CFT which starts in
relatively simple initial states. The initial states are the thermofield double for thermal states …

A bstract We propose that a class of new topologies, for which there is no classical solution,
should be included in the path integral of three-dimensional pure gravity, and that their …
