Natural Inflation with a negative cosmological constant
Chia-Min Lin, Naoto Maki, Kazunori Kohri
In this work, we investigate a cosmic inflation model based on a cosine-type potential with a negative cosmological constant. This model originates from a classical solution of the…
Simple Analytical Solutions of the Wheeler-DeWitt Equation in the Classical Hamilton-Jacobi Limit
Naoto Maki, Chia-Min Lin, Kazunori Kohri
We investigate the Wheeler-DeWitt equation for a flat, homogeneous, and isotropic Universe containing a canonical scalar field with a potential. We show that under the constraint $…
The average equation of state for the oscillating inflaton field of the simplest -attractor E-model
Chia-Min Lin
In this work, we calculate the average equation of state for the oscillating inflaton field of the simplest -attractor E-model. We show that the average equation of state can be…
Uniform Rate Inflation
Chia-Min Lin
In this work, I consider an inflation model with a quadratic potential and a negative cosmological constant. An analytical solution of the equation of motion for the inflaton field…
On the oscillations of the inflaton field of the simplest -attractor T-model
Chia-Min Lin
In this work, we consider homogeneous oscillations of the inflaton field after inflation. In particular, we obtain an analytical result for the (average) equation of state for the…
Hilltop Sneutrino Hybrid Inflation
Chia-Min Lin
In this work, we consider a hilltop version of the (supersymmetric) sneutrino hybrid inflation where the right-handed sneutrino field plays the role of the inflaton field. This mod…
