Sound Speed Resonance of Gravitational Waves in Gauss-Bonnet-coupled inflation
Andrea Addazi, Yermek Aldabergenov, Yifu Cai
We demonstrate the occurrence of Sound Speed Resonances (SSR) in Gauss-Bonnet-coupled inflation across a wide range of coupling functions and parameters. After inflation, the dampe…

The effective field theory approach to the strong coupling issue in gravity with a non-minimally coupled scalar field
Yu-Min Hu, Yang Yu, Yi-Fu Cai +1
The Hamiltonian analysis for gravity implies the existence of at least one scalar-type degree of freedom (DoF). However, this scalar DoF of gravity does not manifest…

Dark matter and baryogenesis in the Fermi-bounce curvaton mechanism
Andrea Addazi, Stephon Alexander, Yi-Fu Cai +1
We elaborate on a toy-model of matter bounce, in which the matter content is constituted by two fermion species endowed with four fermion interaction term. We describe the curvaton…
