Mudassar Sabir, Waqas Ahmed, Yungui Gong +2
We consider a class of helical phase inflation models from the supergravity where the phase component of a complex field acts as an inflaton. This class of models…

Inflation with Gauss-Bonnet coupling
Zhu Yi, Yungui Gong, Mudassar Sabir
We consider inflationary models with the inflaton coupled to the Gauss-Bonnet term assuming a special relation between the two slow-roll parameters and . For…
