Adding flavor to AdS/CFT
Coupling fundamental quarks to QCD in the dual string representation corresponds to adding the open string sector. Flavors therefore should be represented by space‐time filling D‐branes in the dual…
Linear confinement and AdS/QCD

In a theory with linear confinement, such as QCD, the masses squared m^2 of mesons with high spin S or high radial excitation number n are expected, from semiclassical arguments, to grow linearly…
Energy loss of a heavy quark moving through Script N = 4 supersymmetric Yang-Mills plasma
We use the AdS/CFT correspondence to determine the rate of energy loss of a heavy quark moving through = 4 SU(Nc) supersymmetric Yang-Mills plasma at large 't Hooft coupling. Using the dual…

We study the fluctuation spectrum of linearized gravity around non-fine-tuned branes. We focus on the case of an AdS4 brane in AdS§. In this case, for small cosmological constant, the warp factor…
Modeling the fifth dimension with scalars and gravity

A method for obtaining solutions to the classical equations for scalars plus gravity in five dimensions is applied to some recent suggestions for brane-world phenomenology. The method involves only…
Open and closed string interpretation of SUSY CFT's on branes with boundaries
- A. Karch, L. Randall
- Mathematics
- 14 May 2001
We consider certain supersymmetric configurations of intersecting branes and branes ending on branes and analyze the duality between their open and closed string interpretation. The examples we study…
Metallic AdS/CFT

- 26 May 2007
We use the AdS/CFT correspondence to compute the conductivity of massive = 2 hypermultiplet fields at finite baryon number density in an = 4 SU(Nc) super-Yang-Mills theory plasma in the large Nc,…
Branes at orbifolds versus Hanany Witten in six dimensions
- I. Brunner, A. Karch
- Mathematics
- 15 December 1997
We reconstruct non-trivial 6d theories obtained by Blum and Intriligator by considering IIB or SO(32) 5 branes at ALE spaces in the language of Hanany-Witten setups. Using ST duality we make the…
Particle-Vortex Duality from 3D Bosonization

- Physics
- 11 December 2007
We use the holographic proposal for calculating entanglement entropies to determine the boundary entropy of defects in strongly coupled two-dimensional conformal field theories. We study several…
