Tidal stretching of gravitons into classical strings: application to jet quenching with AdS/CFT
Peter Arnold, Phillip Szepietowski, Diana Vaman +1
Previous work has shown that the standard supergravity approximation can break down when using AdS/CFT duality to study certain top-down formulations of the jet stopping problem in…
Comments on a-maximization from gauged supergravity
Phillip Szepietowski
In this paper we study the holographic dual to a-maximization in five-dimensional N = 2 gauged supergravity. In particular, we apply the procedure described by Tachikawa to specifi…
On the Temperature Dependence of the Shear Viscosity and Holography
Sera Cremonini, Umut Gursoy, Phillip Szepietowski
We examine the structure of the shear viscosity to entropy density ratio eta/s in holographic theories of gravity coupled to a scalar field, in the presence of higher derivative co…
Coupling dependence of jet quenching in hot strongly-coupled gauge theories
Peter Arnold, Phillip Szepietowski, Diana Vaman
Previous top-down studies of jet stopping in strongly-coupled QCD-like plasmas with gravity duals have been in the infinite 't Hooft coupling limit lambda -> infinity. They have fo…
