Universal holographic hydrodynamics at finite coupling
Alex Buchel, Robert C. Myers, Miguel F. Paulos +1
We consider thermal plasmas in a large class of superconformal gauge theories described by a holographic dual geometry of the form . In particular, we demonstrate…
Relaxation time of a CFT plasma at finite coupling
Alex Buchel, Miguel Paulos
Following recent formulation of second order relativistic viscous hydrodynamics for conformal fluids, we compute finite coupling corrections to the relaxation time of N=4 supersymm…
Shear viscosity of CFT plasma at finite coupling
Alex Buchel
We present evidence for the universality of the shear viscosity of conformal gauge theory plasmas beyond infinite coupling. We comment of subtleties of computing the shear viscosit…
Resolving disagreement for eta/s in a CFT plasma at finite coupling
Alex Buchel
The ratio of shear viscosity to entropy density in a strongly coupled CFT plasma can be computed using the AdS/CFT correspondence either from equilibrium correlation functions or f…
"Black Universe" epoch in String Cosmology
Alex Buchel, Lev Kofman
String theory compactification involves manifolds with multiple warp factors. For cosmological applications, one often introduces a short, high-energy inflationary throat, and a lo…
Shear viscosity of boost invariant plasma at finite coupling
Alex Buchel
We discuss string theory alpha' corrections in the dual description of the expanding boost invariant N=4 supersymmetric Yang-Mills plasma at strong coupling. We compute finite 't H…
