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…
