We formulate a prescription for computing Minkowski-space 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 two-dimensional conformal field theory dual to the BTZ black hole. Using the prescription, we calculate the Chern-Simons diffusion constant of the finite-temperature = 4 supersymmetric Yang-Mills theory in the strong coupling limit. We explain why the… 

On time-dependent AdS/CFT

We clarify aspects of the holographic AdS/CFT correspondence that are typical of lorentzian signature, to lay the foundation for a treatment of time-dependent gravity and conformal field theory

correspondence , quasinormal modes , and thermal correlators in N = 4 SYM

We use the Lorentzian AdS/CFT prescription to find the poles of the retarded thermal Green’s functions of N = 4 SU(N) SYM theory in the limit of large N and large ’t Hooft coupling. In the process,

Isospin diffusion in thermal AdS/CFT correspondence with flavor

We study the gauge/gravity dual of a finite temperature field theory at finite isospin chemical potential by considering a probe of two coincident D7-branes embedded in the AdS-Schwarzschild black

AdS black holes and thermal Yang-Mills correlators

We study the real time correlators of scalar glueball operators for Yang-Mills theory at finite temperature in flat space. The analytic structure of the frequency space propagator in perturbative

Applications of AdS/CFT in Quark Gluon Plasma

As one of the most important developments in string theory, the AdS/CFT correspondence(or in general gauge/gravity correspondence) encodes a way of using string theory to perform non-perturbative

From Maxwell-Chern-Simons theory in AdS3 towards hydrodynamics in 1 + 1 dimensions

A bstractWe study Abelian Maxwell-Chern-Simons theory in three-dimensional AdS black hole backgrounds for both integer and non-integer Chern-Simons coupling. Such theories can be derived from various

Schwinger-Keldysh propagators from AdS/CFT correspondence

We demonstrate how to compute real-time Green's functions for a class of finite temperature field theories from their AdS gravity duals. In particular, we reproduce the 2 ? 2 Schwinger-Keldysh matrix

A bstractUsing the gauge/gravity correspondence, we study the properties of 2-point correlation functions of finite-temperature strongly coupled gauge field theories, defined on a curved space of

AdS/CFT duality for non-relativistic field theory

We formulate a correspondence between non-relativistic conformal field theories (NRCFTs) in d?1 spatial dimensions and gravitational theories in AdSd+2 backgrounds with one compactified lightlike

From AdS/CFT correspondence to hydrodynamics. II. Sound waves

As a non-trivial check of the non-supersymmetric gauge/gravity duality, we use a near-extremal black brane background to compute the retarded Green's functions of the stress-energy tensor in = 4

What do CFTs tell us about anti-de Sitter spacetimes?

The AdS/CFT conjecture relates quantum gravity on anti-de Sitter (AdS) space to a conformal field theory (CFT) defined on the spacetime boundary. We interpret the CFT in terms of natural analogues of

Vacua, propagators, and holographic probes in AdS/CFT

In this paper we investigate the relation between the bulk and boundary in AdS/CFT. We first discuss the relation between the Poincare and the global vacua, and then study various probes of the bulk

Choptuik scaling and quasinormal modes in the AdS / CFT correspondence

We establish an exact connection between the Choptuik scaling parameter for the three-dimensional Ba\~nados-Teitelboim-Zanelli black hole, and the imaginary part of the quasinormal frequencies for

Quasinormal modes of AdS black holes and the approach to thermal equilibrium

We investigate the decay of a scalar field outside a Schwarzschild anti de Sitter black hole. This is determined by computing the complex frequencies associated with quasinormal modes. There are

On the role of chaos in the AdS / CFT connection

The question of how infalling matter in a pure state forms a Schwarzschild black hole that appears to be at nonzero temperature is discussed in the context of the AdS/CFT connection. It is argued

Anti-de Sitter space and holography

Recently, it has been proposed by Maldacena that large $N$ limits of certain conformal field theories in $d$ dimensions can be described in terms of supergravity (and string theory) on the product of
