Zhi-Guo Liu, Jun Zhang, Yun-Song Piao
We show a model of the slow expansion, in which the scale invariant spectrum of curvature perturbation is adiabatically induced by its increasing mode, by applying a generalized Ga…

Phantom Inflation with A Steplike Potential
Zhi-Guo Liu, Jun Zhang, Yun-Song Piao
The phantom inflation predicts a slightly blue spectrum of tensor perturbation, which might be tested in coming observations. In normal inflation models, the introduction of step i…
