Supersymmetric Branes on AdS_5 x Y^{p,q} and their Field Theory Duals
Felipe Canoura, Jose D. Edelstein, Leopoldo A. Pando Zayas +2
We systematically study supersymmetric embeddings of D-brane probes of different dimensionality in the AdS_5xY^{p,q} background of type IIB string theory. The main technique employ…
Exploring AdS Waves Via Nonminimal Coupling
Eloy Ayón-Beato, Mokhtar Hassaïne
We consider nonminimally coupled scalar fields to explore the Siklos spacetimes in three dimensions. Their interpretation as exact gravitational waves propagating on AdS restrict t…
Topological black holes dressed with a conformally coupled scalar field and electric charge
Cristian Martinez, Juan Pablo Staforelli, Ricardo Troncoso
Electrically charged solutions for gravity with a conformally coupled scalar field are found in four dimensions in the presence of a cosmological constant. If a quartic self-intera…
Phantom Field from Conformal Invariance
Mokhtar Hassaine
We establish a correspondence between a conformally invariant complex scalar field action (with a conformal self-interaction potential) and the action of a phantom scalar field min…
Extended Klein-Gordon Action, Gravity and Non-Relativistic Fluid
Mokhtar Hassaine
We consider a scalar field action for which the Lagrangian density is a power of the massless Klein-Gordon Lagrangian. The coupling of gravity to this matter action is considered.…
Emergent geometry from q-deformations of N=4 super Yang-Mills
David Berenstein, Diego H. Correa
We study BPS states in a marginal deformation of super Yang-Mills on R x S^3 using a quantum mechanical system of q-commuting matrices. We focus mainly on the case where the parame…
