Primordial black holes and oscillating gravitational waves in slow-roll and slow-climb inflation with an intermediate non-inflationary phase
Chengjie Fu, Puxun Wu, Hongwei Yu
We propose a new single field inflation model in which the usual slow-roll inflation is joined to a new period of slow-climb and slow-roll inflation through a short intermediate no…

Scalar induced gravitational waves in inflation with gravitationally enhanced friction
Chengjie Fu, Puxun Wu, Hongwei Yu
We study the scalar induced gravitational wave (GW) background in inflation with gravitationally enhanced friction (GEF). The GEF mechanism, which is realized by assuming a nonmini…
