Tensor Self Energy in a Vector-Tensor Model
A. Buchel, F. A. Chishtie, M. Gagne-Portelance +2
The tensor self energy is computed at one loop order in a model in which a vector and tensor interact in a way that eliminates all tensor degrees of freedom. Divergencies arise whi…
The shear viscosity of gauge theory plasma with chemical potentials
Paolo Benincasa, Alex Buchel, Roman Naryshkin
We consider strongly coupled gauge theory plasma with conserved global charges that allow for a dual gravitational description. We study the shear viscosity of the gauge theory pla…
Dynamical stabilization of runaway potentials at finite density
Alex Buchel, Junji Jia, V. A. Miransky
We study four dimensional non-abelian gauge theories with classical moduli. Introducing a chemical potential for a flavor charge causes moduli to become unstable and start condensi…
Short distance properties of cascading gauge theories
Ofer Aharony, Alex Buchel, Amos Yarom
We study the short distance (large momentum) properties of correlation functions of cascading gauge theories by performing a tree-level computation in their dual gravitational back…
Gauged supergravity from type IIB string theory on Y^{p,q} manifolds
Alex Buchel, James T. Liu
We first construct a consistent Kaluza-Klein reduction ansatz for type IIB theory compactified on Sasaki-Einstein manifolds Y^{p,q} with Freund-Rubin 5-form flux giving rise to min…
Hydrodynamics of Sakai-Sugimoto model in the quenched approximation
Paolo Benincasa, Alex Buchel
We study transport properties of the finite temperature Sakai-Sugimoto model. The model represents a holographic dual to 4+1 dimensional supersymmetric SU(N_c) gauge theory compact…
On jet quenching parameters in strongly coupled non-conformal gauge theories
Alex Buchel
Recently Liu, Rajagopal and Wiedemann (LRW) [hep-ph/0605178] proposed a first principle, nonperturbative quantum field theoretic definition of ``jet quenching parameter'' \hat{q} u…
Higher derivative corrections to near-extremal black holes in type IIB supergravity
Alex Buchel
We discuss string theory alpha' corrections to charged near-extremal black 3-branes/black holes in type IIB supergravity. We find that supersymmetric global AdS_5 x S^5 geometry is…
Inflation on the resolved warped deformed conifold
Alex Buchel
Braneworld inflation on the resolved warped deformed conifold is represented by the dynamics of a D3-brane probe with the world volume of a brane spanning the large dimensions of t…
