Bulkcone Singularities and Complex Geodesics
Ignacio J. Araya, Chantelle Esper, Yueke Jia +2
Thermal correlators in holographic CFTs on a sphere exhibit bulk-cone singularities at points connected by null geodesics in the bulk. The operator product expansion analysis of th…
Bulk Phase Shift and Singularity
Yueke Jia, Manuela Kulaxizi
High-energy scattering of a light particle off a black hole at fixed impact parameter is described by an eikonal phase, which encodes the resulting time delay and angular deflectio…
CFT correlators, -algebras and Generalized Catalan Numbers
Robin Karlsson, Manuela Kulaxizi, Gim Seng Ng +2
In two spacetime dimensions the Virasoro heavy-heavy-light-light (HHLL) vacuum block in a certain limit is governed by the Catalan numbers. The equation for their generating functi…
Stress Tensor Sector of Conformal Correlators
Robin Karlsson, Manuela Kulaxizi, Andrei Parnachev +1
An important part of a CFT four-point function, the stress tensor sector, comprises the exchanges of the stress tensor and its composites. The OPE coefficients of these multi-stres…
Leading Multi-Stress Tensors and Conformal Bootstrap
Robin Karlsson, Manuela Kulaxizi, Andrei Parnachev +1
Near lightcone correlators are dominated by operators with the lowest twist. We consider the contributions of such leading lowest twist multi-stress tensor operators to a heavy-hea…
Subleading Eikonal, AdS/CFT and Double Stress Tensors
Manuela Kulaxizi, Gim Seng Ng, Andrei Parnachev
The eikonal phase which determines the Regge limit of the gravitational scattering amplitude of a light particle off a heavy one in Minkowski spacetimes admits an expansion in the…
