Primordial Non-Gaussianity and Gravitational Waves: Observational Tests of Brane Inflation in String Theory
James E. Lidsey, David Seery
We study brane inflation scenarios in a warped throat geometry and show that there exists a consistency condition between the non-Gaussianity of the curvature perturbation and the…
Non-Gaussian Inflationary Perturbations from the dS/CFT Correspondence
David Seery, James E. Lidsey
We use the dS/CFT correspondence and bulk gravity to predict the form of the renormalized holographic three-point correlation function of the operator which is dual to the inflaton…
An Observational Test of Holographic Inflation
James E. Lidsey, David Seery
Observational consequences of inflationary cosmology in the holographic dual of the Randall-Sundrum type II braneworld scenario, as motivated by the AdS/CFT correspondence, are inv…
Primordial non-gaussianities from multiple-field inflation
David Seery, James E. Lidsey
We calculate the three-point correlation function evaluated at horizon crossing for a set of interacting scalar fields coupled to gravity during inflation. This provides the initia…
Primordial non-gaussianities in single field inflation
David Seery, James E. Lidsey
We calculate the three-point function for primordial scalar fluctuations in a single field inflationary scenario where the scalar field Lagrangian is a completely general function…
An emergent universe from a loop
David J. Mulryne, Reza Tavakol, James E. Lidsey +1
Closed, singularity-free, inflationary cosmological models have recently been studied in the context of general relativity. Despite their appeal, these so called emergent models su…
