Primordial black holes and scalar induced gravitational waves from sound speed resonance in non-minimal derivative coupling inflation model
Li-Shuai Wang, Qiong-Tao Xie, Li-Yang Chen
We investigate an inflationary model with a non-minimal derivative coupling, where the coupling function contains both constant and periodic components. On large scales, the model…
Constraining inflation with nonminimal derivative coupling with the Parkes Pulsar Timing Array third data release
Chang Han, Li-Yang Chen, Zu-Cheng Chen +13
We study an inflation model with nonminimal derivative coupling that features a coupling between the derivative of the inflaton field and the Einstein tensor. This model naturally…
Resonant amplification of curvature perturbations in inflation model with periodical derivative coupling
Li-Yang Chen, Hongwei Yu, Puxun Wu
In this paper, we introduce a weak, transient and periodical derivative coupling between the inflaton field and gravity, and find that the square of the sound speed of the curvatur…
Constant-roll inflation and primordial black holes within Barrow entropic framework
Qihong Huang, Li-Yang Chen, He Huang +2
In this paper, starting from the modified Einstein field equations, we derive the modified scalar spectral index and the modified tensor-to-scalar ratio in Barrow entro…
