Disformal invariance of curvature perturbation
Hayato Motohashi, Jonathan White
We show that under a general disformal transformation the linear comoving curvature perturbation is not identically invariant, but is invariant on superhorizon scales for any theor…

Multi-field formulation of gravitational particle production after inflation
Yuki Watanabe, Jonathan White
We study multi-field inflation models that contain a non-trivial field-space metric and a non-minimal coupling between the gravity and inflaton sectors. In such models it is known…
