Scalar Perturbation Produced at the Pre-inflationary Stage in Eddington-inspired Born-Infeld Gravity
Inyong Cho, Naveen K. Singh
We investigate the scalar perturbation produced at the pre-inflationary stage driven by a massive scalar field in Eddington-inspired Born-Infeld gravity. The scalar power spectrum…

Unimodular Theory of Gravity and Inflation
Inyong Cho, Naveen K. Singh
We investigate inflation and its scalar perturbation driven by a massive scalar field in the unimodular theory of gravity. We introduce a parameter with which the theory is inv…

Tensor-to-Scalar Ratio in Eddington-inspired Born-Infeld Inflation
Inyong Cho, Naveen K. Singh
We investigate the scalar perturbation of the inflation model driven by a massive-scalar field in Eddington-inspired Born-Infeld gravity. We focus on the perturbation at the attrac…
