Transport coefficients from extremal Gauss-Bonnet black holes

We calculate the shear viscosity of strongly coupled field theories dual to Gauss-Bonnet gravity at zero temperature with nonzero chemical potential. We find that the ratio of the shear viscosity

Shear viscosity from Gauss-Bonnet gravity with a dilaton coupling

We calculate the shear viscosity of field theories with gravity duals of Gauss-Bonnet gravity with a nontrivial dilaton using anti-de Sitter/conformal field theory. We find that the dilaton field has

Shear viscosity from effective couplings of gravitons

We calculate the shear viscosity of field theories with gravity duals using Kubo formula by calculating the Green function of dual transverse gravitons and confirm that the value of the shear

Holographic thermalization in Gauss-Bonnet gravity with de Sitter boundary

We introduce higher-derivative Gauss-Bonnet correction terms in the gravity sector, and we relate the modified gravity theory in the bulk to the strongly coupled quantum field theory on a de Sitter

On subextensive corrections to fluid dynamics from gravity

We use the fluid-gravity correspondence to compute subextensive corrections, proportional to the shear tensor, to the energy-momentum tensor of fluids on three-spheres. The dual configurations we

We study real time correlators in strongly coupled = 4 supersymmetric Yang-Mills theory on dS3 ? S1, with antiperiodic boundary conditions for fermions on the circle. When the circle radius is larger

Applications of gauge/gravity dualities with charged Anti-de Sitter black holes

In this thesis, we deal with different applications of the Anti-de Sitter/Conformal Field Theory (AdS/CFT) correspondence. The AdS/CFT correspondence, which is also more generally referred to as

Time-dependent Backgrounds in String Theory and Dualities

This thesis consists of two parts. The first part deals with gauge/gravity duality in the context of anti de Sitter (AdS) spacetimes with de Sitter (dS) boundary, which can be used to study issues

Viscosity Bound Violation in Higher Derivative Gravity

Motivated by the vast string landscape, we consider the shear viscosity to entropy density ratio in conformal field theories dual to Einstein gravity with curvature square corrections. After field

Shear viscosity from AdS born-infeld black holes

We calculate the shear viscosity in the frame of AdS/CFT correspondence for the field theory with a gravity dual of Einstein-Born-Infeld gravity. We find that the ratio of η/s is still the

Viscosity of gauge theory plasma with a chemical potential from AdS/CFT correspondence

We compute the strong coupling limit of the shear viscosity for the N=4 super-Yang-Mill theory with a chemical potential. We use the five-dimensional Reissner-Nordstroem-anti-deSitter black hole, so

Effect of curvature squared corrections in AdS on the viscosity of the dual gauge theory

We use the real-time finite-temperature 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

Viscosity in strongly interacting quantum field theories from black hole physics.

It is provided evidence that this value of shear viscosity to volume density of entropy may serve as a lower bound for a wide class of systems, thus suggesting that black hole horizons are dual to the most ideal fluids.

Shear viscosity of strongly coupled N = 4 supersymmetric Yang-Mills plasma.

Using the anti-de Sitter/conformal field theory correspondence, the shear viscosity eta of the finite-temperature N = 4 supersymmetric Yang-Mills theory is related with the absorption cross section of low-energy gravitons by a near-extremal black three-brane and it is shown that in the limit of zero frequency this cross section coincides with the area of the horizon.
