Violation of the holographic viscosity bound in a strongly coupled anisotropic plasma.
We study the conductivity and shear viscosity tensors of a strongly coupled N=4 super-Yang-Mills plasma which is kept anisotropic by a θ parameter that depends linearly on one of the spatial dimensions. Its holographic dual is given by an anisotropic axion-dilaton-gravity background and has recently been proposed by Mateos and Trancanelli as a model for the preequilibrium stage of quark-gluon p...
متن کاملDebye screening in strongly coupled N = 4 supersymmetric Yang-Mills plasma
Using the AdS/CFT correspondence, we examine the behavior of correlators of Polyakov loops and other operators in N =4 supersymmetric Yang-Mills theory at non-zero temperature. The implications for Debye screening in this strongly coupled non-Abelian plasma, and comparisons with available results for thermal QCD, are discussed.
متن کاملShear viscosity of strongly coupled N = 4 supersymmetric Yang-Mills plasma.
Using the anti-de Sitter/conformal field theory correspondence, we relate the shear viscosity eta of the finite-temperature N = 4 supersymmetric Yang-Mills theory in the large N, strong-coupling regime with the absorption cross section of low-energy gravitons by a near-extremal black three-brane. We show that in the limit of zero frequency this cross section coincides with the area of the horiz...
متن کاملStrongly coupled large N spectrum of two matrices coupled via a Yang-Mills interaction
We consider the large N spectrum of the quantum mechanical hamiltonian of two hermitean matrices coupled via a Yang-Mills interaction. In a framework where one of the matrices is treated exactly and the other is treated as a creation operator impurity, the difference equation associated with the YangMills interaction is derived and solved exactly for two impurities. In this case, the full strin...
متن کاملString Tensions and Representations in Anisotropic (2 + 1)-dimensional Weakly-coupled Yang-mills Theory
In earlier papers we established quark confinement analytically in anisotropic (2 + 1)dimensional Yang-Mills theory with two gauge coupling constants. Here we point out a few features of the confining phase. These are: 1) the string tension in the x-direction as a function of representation obeys a sine law, and 2) static adjoint sources are not confined. [email protected]
