Tachyon Mediated Non-Gaussianity
Bhaskar Dutta, Jason Kumar, Louis Leblond
We describe a general scenario where primordial non-Gaussian curvature perturbations are generated in models with extra scalar fields. The extra scalars communicate to the inflaton…

Simple Bounds from the Perturbative Regime of Inflation
Louis Leblond, Sarah Shandera
We examine the conditions under which a perturbative expansion around an inflating background is valid. When inflation is driven by a single field with a general sound speed, we fi…

Inflation from Wrapped Branes
Melanie Becker, Louis Leblond, Sarah Shandera
We show that the use of higher dimensional wrapped branes can significantly extend the inflaton field range compared to brane inflation models which use D3-branes. We construct a s…
