Neutron star in Logarithmic model of Cartan gravity
Hiroki Sakamoto, Masahiko Taniguchi
Cartan gravity introduces the equivalent scalar-tensor theory by extending the gravity sector. From the solution of the modified Cartan equation leads to the interaction wit…
Robustness of predicted CMB fluctuations in Cartan gravity
Tomohiro Inagaki, Hiroki Sakamoto, Masahiko Taniguchi
The cosmology of the gravity rebuilding by the Cartan formalism is investigated. This is called Cartan gravity. The well-known gravity has been introduced to e…
Exploring the inflation of gravity
Tomohiro Inagaki, Hiroki Sakamoto
The early time expansion of the space-time, namely inflation, is introduced to solve some cosmological problems. gravity is a simple extension of the general relativity to i…
On some parabolic systems arising from a nuclear reactor model with nonlinear boundary conditions
Kosuke Kita, Mitsuharu Ôtani, Hiroki Sakamoto
In this paper, we are concerned with a reaction diffusion system arising from a nuclear reactor model in bounded domains with nonlinear boundary conditions. We show the existence o…
Phenomenological Aspects of Possible Vacua of a Neutrino Flavor Model
Takuya Morozumi, Hideaki Okane, Hiroki Sakamoto +3
We discuss a supersymmetric model with discrete flavor symmetry . The additional scalar fields which contribute masses of leptons in the Yukawa terms are introduced…
An alternative attractor in gauged NJL inflation
Tomohiro Inagaki, Sergei D. Odintsov, Hiroki Sakamoto
We have investigated the attractor structure for the CMB fluctuations in composite inflation scenario within the gauged Nambu-Jona-Lasinio (NJL) model. Such composite inflation rep…
Inflation from the Finite Scale Gauged Nambu-Jona-Lasinio Model
Tomohiro Inagaki, Sergei D. Odintsov, Hiroki Sakamoto
The possibility to construct an inflationary universe scenario for the finite-scale gauged Nambu-Jona-Lasinio model is investigated. This model can be described by the Higgs-Yukawa…
Gauged Nambu-Jona-Lasinio inflation
Tomohiro Inagaki, Sergei D. Odintsov, Hiroki Sakamoto
We investigate the gauged Nambu-Jona-Lasinio model in curved spacetime at the large limit and in slow-roll approximation. The model can be described by the renormalization gr…
