Superhorizon curvature perturbation in ultra-slow-roll inflation
Shu-Lin Cheng, Wolung Lee, Kin-Wang Ng
We study the growth of superhorizon modes in the curvature perturbation during an ultra-slow-roll or a large- phase in single-field inflation. In a simple toy model, we derive t…

Primordial black holes and associated gravitational waves in axion monodromy inflation
Shu-Lin Cheng, Wolung Lee, Kin-Wang Ng
In the axion monodromy inflation, the inflation is driven by the axion with super-Planckian field values in a monomial potential with superimposed sinusoidal modulations. The coupl…
