Defying eternal inflation in warm inflation with a negative running

Abstract:It was pointed out previously [1] that a
sufficiently negative running of the spectral index of curvature
perturbations from (ordinary i.e. cold) inflation is able to prevent eternal inflation from
ever occurring. Here, we reevaluate those original results, but in the
context of warm inflation, in which a substantial radiation component (produced by the inflaton) exists throughout the inflationary period.
We demonstrate that the same general
requirements
found in the context
of ordinary (cold) … Show more
