On Loops in Single Clock Inflation and their IR behavior

This event is part of the HET Seminar Series.

Abstract: Studying loop corrections to inflationary perturbations, with particular emphasis on infrared factors, is important to understand the consistency of the inflationary theory, its predictivity and to establish the existence of the slow-roll eternal inflation phenomena and its recently found volume bound. I will discuss how large IR effects appear in these calculations, how some of them disappear when we compute fluctuations as a function of physically measurable scales, and finally how some of them remain and lead to interesting projection effects.
