Nonlinear Excitations in Inflationary Power Spectra
V Miranda, Wayne Hu, Chen He +1
We develop methods to calculate the curvature power spectrum in models where features in the inflaton potential nonlinearly excite modes and generate high frequency features in the…
Self-accelerating Massive Gravity: Superluminality, Cauchy Surfaces and Strong Coupling
Pavel Motloch, Wayne Hu, Austin Joyce +1
Self-accelerating solutions in massive gravity provide explicit, calculable examples that exhibit the general interplay between superluminality, the well-posedness of the Cauchy pr…
Disformal invariance of curvature perturbation
Hayato Motohashi, Jonathan White
We show that under a general disformal transformation the linear comoving curvature perturbation is not identically invariant, but is invariant on superhorizon scales for any theor…
Running from Features: Optimized Evaluation of Inflationary Power Spectra
Hayato Motohashi, Wayne Hu
In models like axion monodromy, temporal features during inflation which are not associated with its ending can produce scalar, and to a lesser extent, tensor power spectra where d…
