Non-Gaussianity in the warm k-inflation
Chao-Qun Shen, Xiao-Min Zhang, Zhi-Peng Peng +3
This paper presents and investigates non-Gaussian perturbations for the warm k-inflation model that is driven by pure kinetic energy. The two complementary components of the overal…
Two models unifying warm inflation with dark matter and dark energy
Xiao-Min Zhang, Kai Li, Yi-Fu Guo +2
Two models that unify warm inflation with dark matter and dark energy are proposed. In the models, a single scalar field is responsible for the early expansion of the universe thro…
Consistency of a kind of general noncanonical warm inflation
Xiao-Min Zhang, Ang Fu, Kai Li +4
The framework of a kind of noncanonical warm inflation is introduced, and the dynamical equations of this scenario are presented. We propose the slow roll approximations and give s…
Primordial non-Gaussianity in noncanonical warm inflation: three- and four-point correlations
Xiao-Min Zhang, Hong-Yang Ma, Peng-Cheng Chu +1
Non-Gaussianity generated in inflation can be contributed by two parts. The first part, denoted by , is the contribution from four-point correlation of inflaton field…
Primordial non-Gaussianity in warm inflation using formalism
Xiao-Min Zhang, Hong-Yang Ma, Peng-Cheng Chu +2
A formalism is used to study the non-Gaussianity of the primordial curvature perturbation on an uniform density hypersurfaces generated by the warm inflation for the first tim…
