317. The Virasoro Minimal String

L. Eberhardt (IAS Princeton)

26/09/2023, 14:00

The last years have provided us with a number of toy models, where holography can be completely understood and even proved. I will discuss one such recent example. I will introduce a critical string theory in two dimensions and demonstrate that this theory, viewed as two-dimensional quantum gravity on the worldsheet, is equivalent to a double-scaled matrix integral, which provides the...

318. Twisting and untwisting in supergravity, conformal field theory, and holography

I. Saberi (LMU Munich)

26/09/2023, 14:40

I will give a bird's-eye view of some recent developments connected to twists of supergravity theories and to the twisted holography program, trying to highlight structural features that I have found both interesting and fruitful. The focus will be on examples related to M-theory.

319. Black hole bulk-cone singularities

A. Zhiboedov (CERN)

26/09/2023, 16:15

In theories with gravity duals Lorentzian correlators exhibit surprising singularities. These serve as the field-theoretic representation of the emergent bulk causal structure.
In this talk we describe the singularity structure of the thermal two-point function which captures the causal structure of its dual black hole geometry. We explain
how these singularities can be computed in the...

320. Holographic Correlators for all Λs

C. Sleight (Durham)

26/09/2023, 16:55

In this talk we will discuss the central role of Euclidean anti-de Sitter space in defining holographic correlation functions on Lorentzian AdS, dS and flat spaces.
