Effective Field Theory Approach to Cosmological Initial Conditions: Self-Consistency Bounds and Non-Gaussianities
M. Porrati
Effective Field Theory (EFT) is an efficient method for parametrizing unknown high energy physics effects on low energy data. When applied to time-dependent backgrounds, EFT must b…
Massive Gravity in Ads and Minkowski Backgrounds
M. Porrati
I review some interesting features of massive gravity in two maximally symmetric backgrounds: Anti de Sitter space and Minkowski space. While massive gravity in AdS can be seen as…
Holographic Duals of 4D Field Theories
M. Porrati, A. Starinets
We discuss various aspect of the holographic correspondence between 5-d gravity and 4-d field theory. First of all, we describe deformations of N=4 Super Yang-Mills (SYM) theories…
N=6 Supergravity on and the Superconformal Correspondence
S. Ferrara, M. Porrati, A. Zaffaroni
It is argued that N=6 supergravity on , with gauge group corresponds, at the classical level, to a subsector of the ``chiral'' primary operators of N=4 Ya…
Aspects of Dualities
A. Giveon, M. Porrati
In this talk, some aspects of duality symmetries are presented.
Open Strings in Constant Electric and Magnetic Fields
Massimo Porrati
Various properties of open strings in external constant E.M. fields are reviewed. In particular, the charged-particle pair production rate in an external electric field is evaluate…
