Three-form inflation and non-Gaussianity
David J. Mulryne, Johannes Noller, Nelson J. Nunes
We calculate the perturbed action, at second and third order, for a massive three-form field minimally coupled to gravity, and use it to explore the observational predictions of th…

Constraining fast-roll inflation
Johannes Noller
We present constraints on how far single field inflation may depart from the familiar slow-roll paradigm. Considering a fast-roll regime while requiring a (near)-scale-invariant po…

Derivative Chameleons
Johannes Noller
We consider generalized chameleon models where the conformal coupling between matter and gravitational geometries is not only a function of the chameleon field ϕ, but also of its d…
