Einstein-singleton theory and its power spectra in de Sitter inflation
Yun Soo Myung, Taeyoon Moon, Young-Jai Park
We study the Einstein-singleton theory during de Sitter inflation since it provides a way of degenerate fourth-order scalar theory. We obtain an exact solution expressed in terms o…
Revisiting slow-roll inflation in nonminimal derivative coupling with potentials
Yun Soo Myung, Taeyoon Moon, Bum-Hoon Lee
We investigate the slow-roll inflation in the nonminimal derivative coupling (NDC) model with exponential, quadric, and quartic potentials. It was known that this model provides an…
Scale-invariant scalar spectrum from the nonminimal derivative coupling with fourth-order term
Yun Soo Myung, Taeyoon Moon
An exactly scale-invariant spectrum of scalar perturbation generated during de Sitter spacetime is found from the gravity model of the nonminimal derivative coupling with fourth-or…
Scale-invariant tensor spectrum from conformal gravity
Yun Soo Myung, Taeyoon Moon
We study cosmological tensor perturbations generated during de Sitter inflation in the conformal gravity with mass parameter . It turns out that tensor power spectrum is…
