A new branch of inflationary speed limits
Abstract We present a new mechanism for inflation which exhibits a speed limit on scalar motion, generating accelerated expansion even on a steep potential. This arises from explicitly integrating out the short modes of additional fields coupled to the inflaton ϕ via a dimension six operator, yieldi...
