Generating Ekpyrotic Curvature Perturbations Before the Big Bang
Jean-Luc Lehners, Paul McFadden, Neil Turok +1
We analyze a general mechanism for producing a nearly scale-invariant spectrum of cosmological curvature perturbations during a contracting phase preceding a big bang, that can be…

A Signature of Higher Dimensions at the Cosmic Singularity
Paul McFadden
In this thesis we study the dynamics of higher-dimensional gravity in a universe emerging from a brane collision. We develop a set of powerful analytic methods which, we believe, r…

Effective Actions for Heterotic M-Theory
Jean-Luc Lehners, Paul McFadden, Neil Turok
We discuss the moduli space approximation for heterotic M-theory, both for the minimal case of two boundary branes only, and when a bulk brane is included. The resulting effective…
