Quantum tangent kernel
Norihito Shirai, Kenji Kubo, Kosuke Mitarai +1
Quantum kernel method is one of the key approaches to quantum machine learning, which has the advantages that it does not require optimization and has theoretical simplicity. By vi…
Cosmology and Stability in Scalar-Tensor bigravity
Kazuharu Bamba, Yusuke Kokusho, Shin'ichi Nojiri +1
The bigravity models coupled with two scalar fields are constructed. We show that a wide class of the expansion history of the universe, especially corresponding to dark energy and…
Variety of cosmic acceleration models from massive bigravity
Shin'ichi Nojiri, Sergei D. Odintsov, Norihito Shirai
We study the accelerating cosmology in massive bigravity via the reconstruction scheme. The consistent solution of the FRW equations is presented: it includes Big and Little…
Generalized Galileon Model -- cosmological reconstruction and the Vainshtein mechanism --
Norihito Shirai, Kazuharu Bamba, Shota Kumekawa +2
Explicit formulae of the equations in the generalized Galileon models are given. We also develop the formulation of the reconstruction. By using the formulation, we can explicitly…
