Imprints of Dark Photons on Gravitational Wave Polarizations
Kimihiro Nomura, Jiro Soda, Kazushige Ueda +1
We study conversion processes between gravitons and dark photons and reveal the effects of dark photons on the polarization of gravitational waves. Considering cosmological dark ma…
Entanglement of the Vacuum between Left, Right, Future, and Past: Dirac spinor in Rindler spaces and Kasner spaces
Kazushige Ueda, Atsushi Higuchi, Kazuhiro Yamamoto +2
We study the relations of the positive frequency mode functions of Dirac field in 4-dimensional Minkowski spacetime covered with Rindler and Kasner coordinates, and describe the ex…
Relativistic quantum bouncing particles in a homogeneous gravitational field
Ar Rohim, Kazushige Ueda, Kazuhiro Yamamoto +1
In this paper, we study the relativistic effect on the wave functions for a bouncing particle in a gravitational field. Motivated by the equivalence principle, we investigate the K…
