Perturbative unitarity and NEC violation in genesis cosmology
Yong Cai, Ji Xu, Shuai Zhao +1
Explorations of the violation of null energy condition (NEC) in cosmology could enrich our understanding of the very early universe and the related gravity theories. Although a ful…
Holographic non-Gaussianities in general single-field inflation
Hiroshi Isono, Toshifumi Noumi, Gary Shiu +2
We use holographic techniques to compute inflationary non-Gaussianities for general single-field inflation, including models with a non-trivial sound speed. In this holographic app…
Differentiating G-inflation from String Gas Cosmology using the Effective Field Theory Approach
Minxi He, Junyu Liu, Shiyun Lu +4
A characteristic signature of String Gas Cosmology is primordial power spectra for scalar and tensor modes which are almost scale-invariant but with a red tilt for scalar modes but…
Non-Uniqueness of Classical Inflationary Trajectories on a High-Dimensional Landscape
Junyu Liu, Yi Wang, Siyi Zhou
Motivated by the string landscape, inflation may happen on a high dimensional complicated potential. We propose a new way to construct some high dimensional random potentials, and…
