The CFT/AdS correspondence, massive gravitons and a connectivity index conjecture
Ofer Aharony, Adam B. Clark, Andreas Karch
We discuss the general question of which conformal field theories have dual descriptions in terms of quantum gravity theories on anti-de Sitter space. We analyze in detail the case…
Energy loss of a heavy quark moving through N=4 supersymmetric Yang-Mills plasma
C. P. Herzog, A. Karch, P. Kovtun +2
We use the AdS/CFT correspondence to determine the rate of energy loss of a heavy quark moving through N=4 SU(N_c) supersymmetric Yang-Mills plasma at large 't Hooft coupling. Usin…
Chiral Transition of N=4 Super Yang-Mills with Flavor on a 3-Sphere
Andreas Karch, Andy O'Bannon
We use the AdS/CFT correspondence to perform a numerical study of a phase transition in strongly-coupled large-Nc N = 4 Super-Yang-Mills theory on a 3-sphere coupled to a finite nu…
Linear Confinement and AdS/QCD
Andreas Karch, Emanuel Katz, Dam T. Son +1
In a theory with linear confinement, such as QCD, the masses squared m^2 of mesons with high spin S or high radial excitation number n are expected, from semiclassical arguments, t…
