sQGP as hCFT
Alex Buchel, Michal P. Heller, Robert C. Myers
We examine the proposal to make quantitative comparisons between the strongly coupled quark-gluon plasma and holographic descriptions of conformal field theory. In this note, we ca…
Hydrodynamics of the cascading plasma
Alex Buchel
The cascading gauge theory of Klebanov et.al realizes a soluble example of gauge/string correspondence in a non-conformal setting. Such a gauge theory has a strong coupling scale L…
Beyond eta/s = 1/4pi
Alex Buchel, Robert C. Myers, Aninda Sinha
We use low-energy effective description of gauge theory/string theory duality to argue that the Kovtun-Son-Starinets viscosity bound is generically violated in superconformal gauge…
Second order hydrodynamics of a CFT plasma from boost invariant expansion
Alex Buchel, Miguel Paulos
We compute finite coupling correction to a nonlinear second order hydrodynamic coefficient in the boost invariant expansion of the N=4 supersymmetric Yang-Mills plasma. The result…
Tensor Self Energy in a Vector-Tensor Model
A. Buchel, F. A. Chishtie, M. Gagne-Portelance +2
The tensor self energy is computed at one loop order in a model in which a vector and tensor interact in a way that eliminates all tensor degrees of freedom. Divergencies arise whi…
The shear viscosity of gauge theory plasma with chemical potentials
Paolo Benincasa, Alex Buchel, Roman Naryshkin
We consider strongly coupled gauge theory plasma with conserved global charges that allow for a dual gravitational description. We study the shear viscosity of the gauge theory pla…
