Maths HEP Lunchtime Seminars: Holographic Non-Gaussianity

Presented by Paul McFadden, Amsterdam

29 October 2010 13:00 in CM221

We discuss the construction of holographic models for the inflationary epoch. We show how cosmological observables, such as the primordial power spectrum and non-Gaussianities, may be computed from the correlation functions of a dual three-dimensional quantum field theory without gravity. We present a general class of holographic models that are fully consistent with current observational constraints and discuss the distinctive observational signatures they predict for the running of the spectral index and for primordial non-Gaussianity.
