Cancellation of quantum corrections on the soft curvature perturbations

Cancellation of quantum corrections on the soft curvature perturbations

Abstract We study the cancellation of quantum corrections on the superhorizon curvature perturbations from subhorizon physics beyond the single-clock inflation from the viewpoint of the cosmological soft theorem. As an example, we focus on the transient ultra-slow-roll inflation scenario and compute...
