Hillclimbing inflation in metric and Palatini formulations
Ryusuke Jinno, Kunio Kaneta, Kin-ya Oda +1
A new setup of cosmic inflation with a periodic inflaton potential and conformal factor is discussed in the metric and Palatini formulations of gravity. As a concrete example, we f…
On the violent preheating in the mixed Higgs- inflationary model
Minxi He, Ryusuke Jinno, Kohei Kamada +3
It has been argued that the mixed Higgs- model acts as the UV extension of the Higgs inflation, pushing up its cut-off scale in the vacuum close up to the Planck scale. In thi…
Fingerprinting models of first-order phase transitions by the synergy between collider and gravitational-wave experiments
Katsuya Hashino, Ryusuke Jinno, Mitsuru Kakizaki +3
We investigate the sensitivity of future space-based interferometers such as LISA and DECIGO to the parameters of new particle physics models which drive a first-order phase transi…
Machine learning for bounce calculation
Ryusuke Jinno
We study the possibility of using machine learning for the calculation of the bounce action in quantum tunneling. Adopting supervised learning, we train neural network to give the…
