Analog rotating black holes in a magnetohydrodynamic inflow
Sousuke Noda, Yasusada Nambu, Masaaki Takahashi
We present a model of the analog geometry in a magnetohydrodynamic (MHD) flow. For the MHD flow with magnetic pressure-dominated and gas pressure-dominated conditions, we obtain th…
Orbital angular momentum of scalar field generated by gravitational scatterings
Ryusuke Nishikawa, Ken-ichi Nakao, Atsuki Masuda +2
It has been expected that astronomical observations to detect the orbital angular momenta of electromagnetic waves may give us a new insight into astrophysics. Previous works point…
Probability of Boundary Conditions in Quantum Cosmology
Hiroshi Suenobu, Yasusada Nambu
One of the main interest in quantum cosmology is to determine boundary conditions for the wave function of the universe which can predict observational data of our universe. For th…
