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…
