At zero temperature the Coulomb Branch of N = 4 super YangMills theory is described in supergravity by multicenter solutions with D3brane charge. At finite temperature and chemical potential the vacuum degeneracy is lifted, and minima of the free energy are shown to have a supergravity description as rotating black D3branes. In the extreme limit these solutions single out preferred points on the moduli space that can be interpreted as simple distributions of branes — for instance, a uniformly charged planar disc. We exploit this geometrical representation to study the thermodynamics of rotating black D3branes. The low energy excitations of the system appear to be governed by an effective string theory which is related to the singularity in spacetime.

We provide a backgroundindependent formulation of the holographic principle. It permits the construction of embedded hypersurfaces (screens) on which the entire bulk information can be stored at a density of no more than one bit per Planck area. Screens are constructed explicitly for AdS, Minkowski, and de Sitter spaces with and without black holes, and for cosmological solutions. The properties of screens provide clues about the character of a manifestly holographic theory.

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.
Nonextremal gravity duals for fractional D3branes on the conifold

The world volume theory on N regular and M fractional D3branes at the conifold singularity is a nonconformal N = 1 supersymmetric SU(N +M) ×SU(N) gauge theory. In previous work the extremal Type IIB supergravity dual of this theory at zero temperature was constructed. Regularity of the solution requires a deformation of the conifold: this is a reflection of the chiral symmetry breaking. To study the nonzero temperature generalizations nonextremal solutions have to be considered, and in the high temperature phase the chiral symmetry is expected to be restored. Such a solution is expected to have a regular Schwarzschild horizon. We construct an ansatz necessary to study such nonextremal solutions and show that the simplest possible solution has a singular horizon. We derive the system of second order equations in the radial variable whose solutions may have regular horizons.

The equilibrium thermodynamic properties of the SU(N) plasma at finite temperature are studied nonperturbatively in the largeN limit, via lattice simulations. We present highprecision numerical results for the pressure, trace of the energymomentum tensor, energy density and entropy density of SU(N) YangMills theories with N = 3, 4, 5, 6 and 8 colors, in a temperature range from 0.8Tc to 3.4Tc (where Tc denotes the critical deconfinement temperature). The results, normalized according to the number of gluons, show a very mild dependence on N, supporting the idea that the dynamics of the stronglyinteracting QCD plasma could admit a description based on largeN models. We compare our numerical data with general expectations about the thermal behavior of the deconfined gluon plasma and with various theoretical descriptions, including, in particular, the improved holographic QCD model recently proposed by Kiritsis and collaborators. We also comment on the relevance of an AdS/CFT description for the QCD plasma in a phenomenologically interesting temperature range where the system, while still stronglycoupled, approaches a ‘quasiconformal’ regime characterized by approximate scale invariance. Finally, we perform an extrapolation of our
