Scalaron from -gravity as a Heavy Field
Shi Pi, Ying-li Zhang, Qing-Guo Huang +1
We study a model of inflation in which a scalar field is non-minimally coupled to Starobinsky's gravity. After transforming it to the Einstein frame, a new scalar field,…
The status of KAGRA underground cryogenic gravitational wave telescope
KAGRA Collaboration, T. Akutsu, M. Ando +146
KAGRA is a 3-km interferometric gravitational wave telescope located in the Kamioka mine in Japan. It is the first km-class gravitational wave telescope constructed underground to…
Observational signatures of the parametric amplification of gravitational waves during reheating after inflation
Sachiko Kuroyanagi, Chunshan Lin, Misao Sasaki +1
We study the evolution of Gravitational Waves (GWs) during and after inflation as well as the resulting observational consequences in a Lorentz-violating massive gravity theory wit…
Hamiltonian approach to 2nd order gauge invariant cosmological perturbations
Guillem Domènech, Misao Sasaki
In view of growing interest in tensor modes and their possible detection, we clarify the definition of tensor modes up to 2nd order in perturbation theory within the Hamiltonian fo…
The gravitational waves from the first-order phase transition with a dimension-six operator
Rong-Gen Cai, Misao Sasaki, Shao-Jiang Wang
We investigate in details the gravitational wave (GW) from the first-order phase transition (PT) in the extended standard model of particle physics with a dimension-six operator, w…
Thermal activation of thin-shells in anti-de Sitter black hole spacetime
Pisin Chen, Guillem Domènech, Misao Sasaki +1
We investigate thermal activation of thin-shells around anti-de Sitter black holes. Under the thin-shell approximation, we extensively study the parameter region that allows a bubb…
