Conformal field theories have been long known to describe the fascinating universal physics
of scale invariant critical points. They describe continuous phase transitions in fluids …

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 …

We review the recent developments in applying holographic methods to understand
nonequilibrium physics in strongly coupled field theories. The emphasis will be on …

A bstract We take an analytic approach to the CFT bootstrap, studying the 4-pt correlators of
d> 2 dimensional CFTs in an Eikonal-type limit, where the conformal cross ratios satisfy …

A bstract We study the conformal bootstrap for systems of correlators involving nonidentical
operators. The constraints of crossing symmetry and unitarity for such mixed correlators can …

Fundamental principles of local quantum field theory or of quantum gravity can enforce
consistency requirements on the space of consistent low-energy effective field theories. We …

A bstract We develop the embedding formalism for conformal field theories, aimed at doing
computations with symmetric traceless operators of arbitrary spin. We use an indexfree …

We explore the Mellin representation of conformal correlation functions recently proposed by
Mack. Examples in the AdS/CFT context reinforce the analogy between Mellin amplitudes …

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 …

A bstract We develop a new method for decomposing Witten diagrams into conformal
blocks. The steps involved are elementary, requiring no explicit integration, and operate …
