Phase Diagram for Nflation
Iftikhar Ahmad, Yun-Song Piao, Cong-Feng Qiao
Recently, it was showed that there is a large N phase transition in Nflation, in which when the number of fields is large enough, the slow roll inflation phase will disappear. In t…

Spectrum of Curvature Perturbation of Multi-field Inflation with Small-Field Potential
Iftikhar Ahmad, Yun-Song Piao, Cong-Feng Qiao
In this paper, we have studied the spectrum of curvature perturbation of multi-field inflation with general small-field potential. We assume that the isocurvature perturbation may…
