The entanglement entropy is a fundamental quantity, which characterizes the correlations
between sub-systems in a larger quantum-mechanical system. For two sub-systems …

In three spacetime dimensions, general relativity becomes a topological field theory, whose
dynamics can be largely described holographically by a two-dimensional conformal field …

A bstract We discuss holographic models of extremal and non-extremal black holes in
contact with a bath in d dimensions, based on a brane world model introduced in [1]. The …

A bstract Recent progress in our understanding of the black hole information paradox has
lead to a new prescription for calculating entanglement entropies, which involves special …

A bstract Recent work by Zamolodchikov and others has uncovered a solvable irrelevant
deformation of general 2D CFTs, defined by turning on the dimension 4 operator\(T\overline …

A bstract We propose an optimization procedure for Euclidean path-integrals that evaluate
CFT wave functionals in arbitrary dimensions. The optimization is performed by minimizing …

We develop a systematic method for renormalizing the AdS/CFT prescription for computing
correlation functions. This involves regularizing the bulk on-shell supergravity action in a …

We review the formalism of holographic renormalization. We start by discussing
mathematical results on asymptotically anti-de Sitter (AdS) spacetimes. We then outline the …

After a review of symmetries and classical solutions involved in the AdS 3/CFT 2
correspondence, we apply a similar analysis to asymptotically flat spacetimes at null infinity …

A bstract The three sphere partition function, Z, of three dimensional theories with four
supercharges and an R-symmetry is computed using localization, resulting in a matrix …
