Induced Gravitational Waves from Multi-Sound Speed Resonances during Cosmological Inflation
Andrea Addazi, Salvatore Capozziello, Qingyu Gan
We explore the possibility of multi-parametric resonances from time varying sound speed during cosmological inflation. In particular, we fix our set-up to the simpler case beyond a…
