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…
Hydrodynamic dispersion relations at finite coupling
Sašo Grozdanov, Andrei O. Starinets, Petar Tadić
By using holographic methods, the radii of convergence of the hydrodynamic shear and sound dispersion relations were previously computed in the supersymmetric Yang-M…
Thermalization in Large-N CFTs
Robin Karlsson, Andrei Parnachev, Petar Tadić
In d-dimensional CFTs with a large number of degrees of freedom an important set of operators consists of the stress tensor and its products, multi stress tensors. Thermalization o…
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…
The complex life of hydrodynamic modes
Sašo Grozdanov, Pavel K. Kovtun, Andrei O. Starinets +1
We study analytic properties of the dispersion relations in classical hydrodynamics by treating them as Puiseux series in complex momentum. The radii of convergence of the series a…
Black Holes and Conformal Regge Bootstrap
Robin Karlsson, Manuela Kulaxizi, Andrei Parnachev +1
Highly energetic particles traveling in the background of an asymptotically AdS black hole experience a Shapiro time delay and an angle deflection. These quantities are related to…
