Month: September 2020

On October 29 we will have a seminar by

Alberto Zaffaroni (Università di Milano Bicocca)

Title: Universal black holes in AdS

Abstract:
In this talk I discuss a universal microscopic counting for AdS black holes that arise as solutions of the half-maximal gauged supergravity in four and five dimensions. These solutions can be embedded in all AdS M-theory and type II string backgrounds with sixteen supercharges and provide an infinite set of examples dual to N = 2 and N = 4 conformal field theories in four and three dimensions, respectively.

On October 1st we will have a seminar by

Alexander Zhiboedov (CERN)

Title: Conformal Bootstrap in Mellin Space

Abstract:
I will talk about recent progress in analytic approaches to the conformal bootstrap. I will introduce Mellin space as a convenient tool to perform both perturbative and nonperturbative computations in conformal field theories. I will discuss dispersion relations in Mellin space, the sum rules that they lead to, and applications thereof. These include the Wilson-Fisher model in d=4-eps dimensions and holographic computations. I will also talk about generalization of these techniques to finite temperatures.
