➤ Nejc Čeplak (TCD): Using the OPE to look beyond horizons

Black hole singularities leave distinct imprints on holographic correlation functions, traceable to bouncing geodesics: null geodesics that begin on one boundary of an eternal AdS black hole, reflect off the singularity, and reach a different boundary. Using the Operator Product Expansion (OPE), I will show that divergences in the complex-time plane of holographic correlation functions occur precisely at positions predicted by these geodesics, establishing a direct connection between the analytic structure of holographic correlators and black hole singularities. In this talk, I will discuss both neutral (Schwarzschild) and electrically charged black holes in AdS. In the latter case, I will show how the rich causal structure of the interior, including information about the inner horizon, is encoded in the analytic properties of holographic correlation functions.
