Potential Surge Preheating: enhanced resonance from potential features
Pankaj Saha, Yuko Urakawa
We investigate the effects of local features in the inflationary potential on the preheating dynamics after inflation. We show that a small feature in the potential can enhance the…

Probing baryogenesis with gravitational waves
Yanou Cui, Anish Ghoshal, Pankaj Saha +1
Affleck-Dine (AD) baryogenesis is compelling yet challenging to probe because of the high-energy physics involved. We demonstrate that this mechanism can be generically realized wi…
