Perturbation, non-Gaussianity, and reheating in a Gauss-Bonnet -attractor model
Motivated by α-attractor models, in this paper we consider a Gauss-Bonnet inflation with an
E-model-type of potential. We consider the Gauss-Bonnet coupling function to be the same …

Observational Viability of an Inflation Model with E-model Nonminimal Derivative Coupling
By starting with a two-fields model in which the fields and their derivatives are nonminimally
coupled to gravity, and then by using a conformal gauge, we obtain a model in which the …

Large non-gaussianity in a non-minimally coupled derivative inflationary model with Gauss-Bonnet correction
We study a nonminimal derivative inflationary model in the presence of the Gauss-Bonnet

Testing an inflation model with nonminimal derivative coupling in the light of Planck 2015 data
We study the dynamics of a generalized inflationary model in which both the scalar field and
its derivatives are coupled with the gravity. We consider a general form of the nonminimal …

[HTML][HTML] The size of local bispectrum and trispectrum in a non-minimal inflation
Focusing on the local type primordial non-Gaussianities, we study the bispectrum and
trispectrum during a non-minimal slow-roll inflation. We use the so-called δN formalism to …

Testing a two field inflation beyond the slow-roll approximation
We consider a model of two field inflation, containing an ordinary scalar field and a Dirac-
