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…
Cosmological Coincidence without Fine Tuning
Joohan Lee, Tae-Hoon Lee, Phillial Oh +1
We present a simple cosmological model in which a single, non-minimally coupled scalar field with a quartic potential is responsible for both inflation at early times and accelerat…
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…
Degeneracy pressure of relic neutrinos and cosmic coincidence problem
Tae Hoon Lee
We consider the universe as a huge -sphere formed with degenerate relic neutrinos and suggest that its constant energy density play a role of an effective cosmological constan…
