This discussion will focus on the question of how locality on distance scales smaller than the AdS radius can emerge from a CFT. We will introduce Landau singularities as a sign of locality in QFT, and discuss the extent to which they are present...

A supersymmetric sector of N=(0,2) theories in two dimensions defined by taking the cohomology of one of the supercharges is known to carry the structure of a chiral algebra. I will talk about some general and more concrete properties of such...

I'll start reviewing some aspects of my paper with K. Hori [1] about localization of Gauged Linear Sigma Models (GLSM) on a disc/hemisphere. The focus is on a special class of boundary conditions corresponding to B-branes. I'll then review the...

Jets are particularly interesting probes to study the formation and evolution of quark-gluon plasma, as created in heavy ion collisions. In this talk I will briefly review attempts to describe the jet evolution in holography, and will argue that...

I will review recent progress in the computation of multiloop scattering amplitudes using the pure spinor formalism of the superstring and make comments about future directions.

I would like to discuss the idea that CFT entanglement explains gravity in AdS/CFT. van Raamsdonk et al. [1] showed that the linearized Einstein equations about the AdS vacuum are equivalent to the entanglement first law in CFT’s, assuming the Ryu...

In this talk, we will use the holographic entanglement entropy formulas to derive a simple expression for the modular hamiltonian in bulk perturbation theory, for an arbitrary state and subregion. This remarkably simple expression has interesting...

I will discuss the status of the controversial "entropy bounds" proposed by Bekenstein and Bousso, as well as the reinterpretation of these bounds by Casini and others which made them actually true in QFT.

We review recent results of the renormalization group functions of scalar quantum field theories in various spacetime dimensions and their application to recent ideas in conformal field theories as a prelude to the extension to gauge theories. At...
