Radiation drag driven mass accretion in clumpy interstellar medium: implications for the supermassive black hole-to-bulge relation
Nozomu Kawakatu, Masayuki Umemura
We quantitatively scrutinize the effects of the radiation drag arising from the radiation fields in a galactic bulge in order to examine the possibility that the radiation drag cou…
Reionization of an Inhomogeneous Universe
M. Umemura, T. Nakamoto, H. Susa
Full radiative transfer in 3D space has been solved to pursue the reionization history in an inhomogeneous universe. It has been shown that the reionization of an inhomogeneous uni…
Vortex Lattices in Quantum Mechanics
Tsunehiro Kobayashi
Vortex lattices are constructed in terms of linear combinations of solutions for Scrödinger equation with a constant potential. The vortex lattices are mapped on the spaces with tw…
Zero Energy Solutions and Vortices in Schroedinger Equations
Tsunehiro Kobayashi, Toshiki Shimbori
All two-dimensional Schrödinger equations with symmetric potentials \break is shown to have zero energy states…
