Where's Kasner? OPE Signature of Kasner Exponents
Nejc Čeplak, Samuel Valach
At large , the analytic structure of holographic thermal correlation functions contains non-trivial information about the near-singularity region of dual black holes. In particu…
Quasinormal modes as exterior probes of black hole interiors in our Universe
Sašo Grozdanov, Vita Movrin, Samuel Valach
We consider a scenario in which a black hole is enclosed in a reflecting timelike cavity and linearly perturbed. For the resulting quasinormal spectra of gravitational, electromagn…
Bouncing Geodesics, Singularities, and the Cavity Thermal Product Formula in Asymptotically Flat and de Sitter Black Holes
Sašo Grozdanov, Vita Movrin, Samuel Valach
We investigate the existence and implications of ``bouncing geodesics'' in asymptotically flat Schwarzschild and Schwarzschild--de Sitter black holes. These trajectories, which pro…
Bouncing geodesics, black hole singularities, and singularities of thermal correlators
Sašo Grozdanov, Samuel Valach, Mile Vrbica
Bouncing geodesics have been used as valuable probes of black hole singularities. In the dual boundary theory, the presence of bouncing geodesics is encoded in the analytic structu…
Fooling the Censor: Going beyond inner horizons with the OPE
Nejc Čeplak, Hong Liu, Andrei Parnachev +1
The analytic structure of holographic correlation functions at finite temperature contains information about curvature singularities of black holes in AdS. We compute the Operator…
Thermal Correlators and Black Holes: From Infinity to Singularity
Samuel Valach
This thesis explores thermal correlation functions in conformal field theories (CFTs) and their connection to black hole geometry within the AdS/CFT correspondence, using a near-bo…
Black Hole Singularity from OPE
Nejc Čeplak, Hong Liu, Andrei Parnachev +1
Eternal asymptotically AdS black holes are dual to thermofield double states in the boundary CFT. It has long been known that black hole singularities have certain signatures in bo…
Thermal Stress Tensor Correlators near Lightcone and Holography
Chantelle Esper, Kuo-Wei Huang, Robin Karlsson +2
We consider thermal stress-tensor two-point functions in holographic theories in the near-lightcone regime and analyse them using the operator product expansion (OPE). In the limit…
Freedom near Lightcone and ANEC Saturation
Kuo-Wei Huang, Robin Karlsson, Andrei Parnachev +1
Averaged Null Energy Conditions (ANECs) hold in unitary quantum field theories. In conformal field theories, ANECs in states created by the application of the stress tensor to the…
Thermal Stress Tensor Correlators, OPE and Holography
Robin Karlsson, Andrei Parnachev, Valentina Prilepina +1
In strongly coupled conformal field theories with a large central charge important light degrees of freedom are the stress tensor and its composites, multi-stress tensors. We consi…
