Parametrically amplified super-radiance towards hot big bang universe
Motohiko Yoshimura, Kunio Kaneta, Kin-ya Oda
We propose a mechanism of preheating stage after inflation, using a new idea of parametrically amplified super-radiance. Highly coherent state, characterized by macro-coherence of…
Pseudo-Nambu-Goldstone Boson Production from Inflaton Coupling during Reheating
Kunio Kaneta, Sung Mook Lee, Kin-ya Oda +1
The existence of pseudo-Nambu-Goldstone boson (pNGB) fields is a common feature in many models beyond the Standard Model, characterized by their exclusive derivative couplings. Thi…
Accelerating universe at early and late times in extended Jordan-Brans-Dicke gravity
Kunio Kaneta, Kin-ya Oda, Motohiko Yoshimura
We propose a scenario that can explain the early-time inflation and the late-time dark energy within a unified framework. A scalar potential combining power-law and exponential typ…
