Gravitational and dark wave emission at binary merger

Kunio Kaneta, Kin-ya Oda, Motohiko Yoshimura

The recently proposed formalism of extended Jordan-Brans-Dicke gravity makes it possible to calculate energy loss rate due to both gravitational wave and scalar field (giving the o…

Periodic super-radiance in Er:YSO crystal

Hideaki Hara, Junseok Han, Yasutaka Imai +5

We observed periodic optical pulses from an Er:YSO crystal during irradiating with an continuous-wave excitation laser. We refer to this new phenomenon as "periodic super-radiance"…

Constraints on extended Jordan-Brans-Dicke gravity

Kunio Kaneta, Kin-ya Oda, Motohiko Yoshimura

Cosmological analysis of extended Jordan-Brans-Dicke (eJBD) gravity is presented in the Einstein metric frame in which gravitational interaction is readily understandable. Our form…

Axion cosmology in the presence of non-trivial Nambu-Goldstone modes

Motohiko Yoshimura

Axion cosmology is reexamined taking into account effect of kinetic pseudo Nambu-Goldstone modes, with its importance recently pointed out. When Peccei-Quinn (PQ) symmetry is broke…

Quantum dots as a probe of fundamental physics: Deviation from exponential decay law

A. Yoshimi, M. Tanaka, M. Yoshimura

We explore a possibility of measuring deviation from the exponential decay law in pure quantum systems. The power law behavior at late times of decay time profile is predicted in q…

QED background against atomic neutrino process with initial spatial phase

Minoru Tanaka, Koji Tsumura, Noboru Sasao +2

Atomic deexcitation emitting a neutrino pair and a photon is expected to provide a novel method of neutrino physics if it is enhanced by quantum coherence in a macroscopic target.…
