Proving the absence of large one-loop corrections to the power spectrum of curvature perturbations in transient ultra-slow-roll inflation within the path-integral approach

Ryodai Kawaguchi, Shinji Tsujikawa, Yusuke Yamada

We revisit one-loop corrections to the power spectrum of curvature perturbations in an inflationary scenario containing a transient ultra-slow-roll (USR) period. In Ref.[1], it…

Roles of boundary and equation-of-motion terms in cosmological correlation functions

Ryodai Kawaguchi, Shinji Tsujikawa, Yusuke Yamada

We revisit the properties of total time-derivative terms as well as terms proportional to the free equation of motion (EOM) in a Schwinger-Keldysh formalism. They are relevant to t…
