The ζ–ζ correlator is time dependent

摘要: Abstract We comment on the recent arguments by Senatore and Zaldarriaga that loop corrections to ζ – correlator cannot grow with time after first horizon crossing. emphasize need search for such secular dependence in whose in–out matrix elements are infrared singular an infinite spatial manifold. Then we give examples of from pure quantum gravity scalar potential models. Finally, point out this arises inflationary particle production is therefore unlikely endanger preservation super-horizon correlations as a record inflation.
