A complete analysis of inflation with piecewise quadratic potential
Xinpeng Wang, Xiao-Han Ma, Misao Sasaki
We conduct a thorough study of the comoving curvature perturbation in single-field inflation with two stages, represented by a piecewise quadratic potential, where bo…

Enhanced Curvature Perturbation and Primordial Black Hole Formation in Two-stage Inflation with a break
Xinpeng Wang, Ying-li Zhang, Misao Sasaki
We investigate a model of -gravity with a non-minimally coupled scalar field that gives rise to two-stage inflation with a break, that is, with an intermediate stage where inf…
