gravity with broken Weyl gauge symmetry, cosmological backreaction, and its effects on CMB anisotropy
Jiwon Park, Tae Hoon Lee
We propose a new class of theory where its Weyl gauge symmetry is broken in the primordial era of the universe. This symmetry forces one to adopt a new scalar field, namely…
An exact solution of the higher-order gravity in standard radiation-dominated era
Chae-min Yun, Jubin Park, Myung-Ki Cheoun +1
We report that the standard evolution of radiation-dominated era (RDE) universe is a sufficient condition for solving a sixth order gravitational field equation…
Probing Primordial Symmetry Breaking with Cosmic Microwave Background Anisotropy
Jiwon Park, Tae Hoon Lee
There have been vigorous research attempts to test various modified gravity theories by usingphysics of the cosmic microwave background (CMB). Meanwhile, symmetry breaking such as…
Dynamical analysis of Brans-Dicke Universe with inverse power-law effective potential
Jonghyun Sim, Jiwon Park, Tae Hoon Lee
We study Brans-Dicke cosmology with an inverse power-law effective potential. By using dynamical analyses, we search for fixed points corresponding to the radiation-like matter and…
Dark spinor model with torsion and cosmology
Seyen Kouwn, Joohan Lee, Tae Hoon Lee +1
We study cosmological consequences of the dark spinor model when torsion is included. Only some components of the torsion are allowed to be non-vanishing in homogeneous and isotrop…
Conformally-coupled dark spinor and FRW universe
Joohan Lee, Tae Hoon Lee, Phillial Oh
We study conformal coupling of dark spinor fields to gravity and calculate the energy density and the pressure of the spinor in FRW spacetime. We consider the renormalizable potent…
