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…
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…
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…
Three-photon annihilation of the electron-positron pairs
A. M. Frolov
Three-photon annihilation of the electron-positron pairs (= pairs) is considered in the electron rest frame. The energy of the incident positron can be arbitrary.…
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…
