We review recent progress on the information paradox. We explain why exponentially small
correlations in the radiation emitted by a black hole are sufficient to resolve the original …

We give a pedagogical review of how concepts from quantum information theory build up
the gravitational side of the anti-de Sitter/conformal field theory correspondence. The review …

A bstract We propose that holographic entanglement entropy can be calculated at arbitrary
orders in the bulk Planck constant using the concept of a “quantum extremal surface”: a …

In ordinary quantum field theory, one can define the algebra of observables in a given
region in spacetime, but in the presence of gravity, it is expected that this notion ceases to be …

A bstract We use holography to study sensitive dependence on initial conditions in strongly
coupled field theories. Specifically, we mildly perturb a thermofield double state by adding a …

A bstract We study products of precursors of spatially local operators,\({W_x} _ {{}
_n}(tn)\cdot\cdot\cdot {W} _ {x_1}\left ({t} _1\right)\), where W x (t)= e− iHt W xe iHt. Using …

The locality of bulk physics at distances below the AdS length scale is one of the remarkable
aspects of AdS/CFT duality, and one of the least tested. It requires that the AdS radius be …

A bstract We describe the experience of an observer falling into a black hole using the
AdS/CFT correspondence. In order to do this, we reconstruct the local bulk operators …

In previous work we proposed a field theory model for multiple M2-branes based on an
algebra with a totally antisymmetric triple product. In this paper we gauge a symmetry that …

The Lorentzian anti-de Sitter/conformal field theory correspondence implies a map between
local operators in supergravity and nonlocal operators in the CFT. By explicit computation …
