An analytical approximation of the evolution of the primordial curvature perturbation in the ultraslow-roll inflation
Ji-Xiang Zhao, Nan Li
Cosmic inflation can enter an ultraslow-roll (USR) stage, if there is a plateau on the inflaton potential. During this stage, the primordial curvature perturbation …

Primordial black holes and scalar-induced gravitational waves from the perturbations on the inflaton potential in peak theory
Ji-Xiang Zhao, Xiao-Hui Liu, Nan Li
A perturbation on the background inflaton potential can lead inflation into the ultraslow-roll stage and can thus remarkably enhance the power spectrum of th…
