The Thermal Seminars are a series of webinars on finite temperature quantum field theories, conformal field theories, and related topics, from holography, to black holes and bootstrap approaches.
The spirit of the webinars is to establish new connections in the community of people interested about thermal effects, offering a platform to meet and discuss the state of the art of the literature.
The Thermal Seminars are organized by Julien Barrat (DESY), Deniz Bozkurt (U. Hamburg), Enrico Marchetto (DESY), Alessio Miscioscia (YITP, Stony Brook).

Bouncing off a stringy singularity
Abstract: I will discuss boundary signatures of black hole geometries in holography. In particular, a sharp signature of the black hole singularity in holography is a divergence in the boundary thermal two-point function at a specific point in the complex time plane. This divergence arises from a null geodesic that bounces off the black hole singularity. At finite ’t Hooft coupling, stringy corrections to the bulk dynamics cannotbe neglected, and the fate of the bouncing geodesic is an open question. I will discuss how bouncing geodesics appear from QNMs and propose a simple scenario of how these singularities are smoothed out. This scenario resembles closely what happens in the SYK model. Based on 2511.09616 with Matthew Dodelson and Cristoforo Iossa.
