3-D Interacting CFTs and Generalized Higgs Phenomenon in Higher Spin Theories on AdS
L. Girardello, M. Porrati, A. Zaffaroni
We study a duality, recently conjectured by Klebanov and Polyakov, between higher-spin theories on AdS_4 and O(N) vector models in 3-d. These theories are free in the UV and intera…
Observations on the Holographic Duals of 4-D Extremal Black Holes
S. Ferrara, M. Porrati
We argue that extremal black holes of N=4 Poincare supergravity coupled to conformal matter have a quantum-exact dual 5-d description in the maximally supersymmetric extension of t…
N=1 No-Scale Supergravity from IIB Orientifolds
S. Ferrara, M. Porrati
We describe the low-energy effective theory of N=1 spontaneously broken supegravity obtained by flux-induced breaking in the presence of n D3 branes. This theory can be obtained by…
On the Graviton Self Energy in AdS_4
Massimo Porrati, Andrei Starinets
We consider Einstein gravity coupled to a CFT made of a single free conformal scalar in 4-d Anti de Sitter space. This simple case is rich enough to explain an unexpected gravitati…
