Inflection Point Inflation in Supergravity
Manuel Drees, Wenbin Zhao
In this paper, we study the inflection point inflation generated by a polynomial superpotential and a canonical Kähler potential under the supergravity framework, where only one ch…

Gravitational Dark Matter Production in Supergravity -Attractor Inflation
Chenhuan Wang, Wenbin Zhao
We consider gravitational particle production (GPP) of dark matter (DM) under a supergravity framework, where the -attractor inflation model is used. The particle spectrum is co…
