Tensors, non-Gaussianities, and the future of potential reconstruction
Brian A. Powell, Konstantinos Tzirakis, William H. Kinney
We present projections for reconstruction of the inflationary potential expected from ESA's upcoming Planck Surveyor CMB mission. We focus on the effects that tensor perturbations…
Non-canonical generalizations of slow-roll inflation models
Konstantinos Tzirakis, William H. Kinney
We consider non-canonical generalizations of two classes of simple single-field inflation models. First, we study the non-canonical version of "ultra-slow roll" inflation, which is…
Inflation over the hill
Konstantinos Tzirakis, William H. Kinney
We calculate the power spectrum of curvature perturbations when the inflaton field is rolling over the top of a local maximum of a potential. We show that the evolution of the fiel…
