Second order solutions of cosmological perturbation in the matter dominated era / Hwang, Jai-chan (Kyungpook Natl. U. ; Korea Inst. Advanced Study, Seoul) ; Noh, Hyerim (KASI, DaeJeon) ; Gong, Jinn-Ouk (CERN)
We present the growing mode solutions of cosmological perturbations to the second order in the matter dominated era. We also present several gauge-invariant combinations of perturbation variables to the second order in most general fluid context. [...]

Conformal invariance of curvature perturbation / Gong, Jinn-Ouk (CERN) ; Hwang, Jai-chan (Kyungpook Natl. U.) ; Park, Wan-Il (Korea Inst. Advanced Study, Seoul) ; Sasaki, Misao (Korea Inst. Advanced Study, Seoul ; Kyoto U., Yukawa Inst., Kyoto) ; Song, Yong-Seon (Korea Inst. Advanced Study, Seoul)
We show that in the single component situation all perturbation variables in the comoving gauge are conformally invariant to all perturbation orders. Generally we identify a special time slicing, the uniform-conformal transformation slicing, where all perturbations are again conformally invariant to all perturbation orders. [...]

Non-linear corrections to inflationary power spectrum / Gong, Jinn-Ouk (Leiden U. ; CERN) ; Noh, Hyerim (KASI, DaeJeon) ; Hwang, Jai-chan (Kyungpook Natl. U.)
We study non-linear contributions to the power spectrum of the curvature perturbation on super-horizon scales, produced during slow-roll inflation driven by a canonical single scalar field. We find that on large scales the linear power spectrum completely dominates and leading non-linear corrections remain totally negligible, indicating that we can safely rely on linear perturbation theory to study inflationary power spectrum.
