Xingang Chen, Yi Wang
We introduce a generic mechanism that can extend the effects of relic anisotropies at the beginning of inflation to relatively much shorter scales in density perturbations. This is…

Large Local Non-Gaussianity from General Single-field Inflation
Qing-Guo Huang, Yi Wang
We investigate the non-Gaussian signatures of ultra slow-roll inflation. The bispectrum and the trispectrum are calculated with general initial conditions. The trispectrum is of lo…

Inflation, Cosmic Perturbations and Non-Gaussianities
Yi Wang
We review the theory of inflationary perturbations. Perturbations at both linear and nonlinear orders are reviewed. We also review a variety of inflation models, emphasizing their…
