The effect of varying sound velocity on primordial curvature perturbations
Masahiro Nakashima, Ryo Saito, Yu-ichi Takamizu +1
We study the effects of sudden change in the sound velocity on primordial curvature perturbation spectrum in inflationary cosmology, assuming that the background evolution satisfie…
