Propagation of Light in Cantor Media
Masanori Yamanaka, Mahito Kohmoto
We numerically find that transmission coefficients have a rich structure as a function of wavelength in Cantor media. Complete transmission and complete reflection are observed. We…
Statistics of Spectra for One-dimensional Quasi-Periodic Systems at the Metal-Insulator Transition
Yoshihiro Takada, Kazusumi Ino, Masanori Yamanaka
We study spectral statistics of one-dimensional quasi-periodic systems at the metal-insulator transition. Several types of spectral statistics are observed at the critical points,…
Detecting Gapless Excitations above Ferromagnetic Domain Walls
Tohru Koma, Masanori Yamanaka
In a two or three dimensional ferromagnetic XXZ model, a low energy excitation mode above a magnetic domain wall is gapless, whereas all of the usual spin wave excitations moving a…
Quantization of Hall Conductance in Double Exchange Systems: Topology and Lattice Gauge Field
Atsuo Satou, Masanori Yamanaka
We study quantization conditions of the Hall conductivity for a two dimensional system described by a double exchange Hamiltonian with and without an external magnetic field. This…
Scattering of Conduction Electrons by a Ferromagnetic Domain Wall
Masanori Yamanaka, Tohru Koma
We study the scattering of an electron by a ferromagnetic domain wall of the quantum Heisenberg-Ising model (XXZ model) with certain boundary conditions. The spin of the electron i…
