Weyl gravity in higher dimensions
Taeyoon Moon, Phillial Oh
We consider higher dimensional gravity in which the four dimensional spacetime and extra dimensions are not treated on an equal footing. The anisotropy is implemented in the ADM de…
Spontaneous symmetry breaking in 5D conformally invariant gravity
Taeyoon Moon, Phillial Oh
We explore the possibility of the spontaneous symmetry breaking in 5D conformally invariant gravity, whose action consists of a scalar field nonminimally coupled to the curvature w…
Inflaton decay and reheating in nonminimal derivative coupling
Yun Soo Myung, Taeyoon Moon
We investigate the inflaton decay and reheating period after the end of inflation in the non-minimal derivative coupling (NDC) model with chaotic potential. In general, this model…
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…
