Abstract: We formulate a prescription for computing Minkowskispace correlators from AdS/CFT correspondence. This prescription is shown to give the correct retarded propagators at zero temperature in four dimensions, as well as at finite temperature in the twodimensional conformal field theory dual to the BTZ black hole. Using the prescription, we calculate the ChernSimons diffusion constant of the finitetemperature N = 4 supersymmetric YangMills theory in the strong coupling limit. We explain why the quasinormal frequencies of the asymptotically AdS background correspond to the poles of the retarded Green’s function of the boundary conformal field theory.
Effect of curvature squared corrections in AdS on the viscosity of the dual gauge theory

"... Abstract: We use the realtime finitetemperature AdS/CFT correspondence to compute the effect of general R 2 corrections to the gravitational action in AdS space on the shear viscosity of the dual gauge theory. The R 2 terms in AdS5 are determined by the central charges of the CFT. It seems that th ..."

Abstract: We use the realtime finitetemperature AdS/CFT correspondence to compute the effect of general R 2 corrections to the gravitational action in AdS space on the shear viscosity of the dual gauge theory. The R 2 terms in AdS5 are determined by the central charges of the CFT. It seems that the conjectured lower bound of 1/4π on the viscositytoentropy ratio can be violated. Contents

We consider the low energy limit of a stack of N Mbranes at finite temperature. In this limit, the Mbranes are well described, via the AdS/CFT correspondence, in terms of classical solutions to the eleven dimensional supergravity equations of motion. We calculate Minkowski space twopoint functions on these Mbranes in the longdistance, lowfrequency limit, i.e. the hydrodynamic limit, using the prescription of Son and Starinets [hepth/0205051]. From these Green’s functions for the Rcurrents and for components of the stressenergy tensor, we extract two kinds of diffusion constant and a viscosity. The N dependence of these physical quantities may help lead to a better understanding of Mbranes. The interacting, superconformal field theories (SCFT) living on a stack of N M2 or M5branes are not well understood. An improved understanding of these Mbranes should lead eventually to a better understanding of Mtheory itself, a theory that encompasses all the different super string theories and is one of the best hopes for a quantum theory of gravity.
String Theory and Quantum Chromodynamics

Emphasis is placed on conciseness and conceptual aspects rather than on technical details. Topics covered include the largeN c limit of gauge theories, the gravit ..."

I review recent progress on the connection between string theory and quantum chromodynamics in the context of the gauge/gravity duality. Emphasis is placed on conciseness and conceptual aspects rather than on technical details. Topics covered include the largeN c limit of gauge theories, the gravitational description of gauge theory thermodynamics and hydrodynamics, and confinement/deconfinement thermal phase transitions. 1 Lectures given at the RTN Winter School on “Strings, Supergravity and Gauge Theories ” at CERN
ENERGY LOSS IN A STRONGLY COUPLED THERMAL MEDIUM AND THE GAUGESTRING DUALITY

We review methods developed in the gaugestring duality to treat energy loss by energetic probes of a strongly coupled thermal medium. After introducing the black hole description of the thermal medium, we discuss the trailing string behind a heavy quark and the drag force that it implies. We then explain how to solve the linearized Einstein equations in the presence of the trailing string and extract from the solutions the energy density and the Poynting vector of the dual gauge theory. We summarize some efforts to compare these calculations to heavy ion phenomenology.

We study the matter produced in heavy ion collisions assuming that this matter is strongly interacting and employing AdS/CFT correspondence to investigate its dynamics. At late proper times τ we show that Bjorken hydrodynamics solution, obtained recently by Janik and Peschanski using gaugegravity duality [1], can be singled out by simply requiring that the metric tensor is a real and singlevalued function of the coordinates everywhere in the bulk, without imposing any constraints on the curvature invariant. At early proper times we use similar strategy to show that the energy density ǫ approaches a constant as τ → 0. We therefore demonstrate that the strong coupling dynamics incorporates the isotropization transition in heavy ion collisions. By matching our earlytime regime with the latetime one of Janik and Peschanski we estimate the isotropization time at RHIC to be approximately τiso ≈ 0.3 fm/c, in good agreement with results of hydrodynamic simulations.
