Graviton Production from Inflaton Condensate: Boltzmann vs Bogoliubov
Chenhuan Wang, Yong Xu, Wenbin Zhao
We study graviton production from an oscillating inflaton condensate during reheating by systematically comparing Boltzmann and Bogoliubov descriptions for inflaton potentials of t…

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…
