Insensitivity of Quantized Hall Conductance to Disorder and Interactions
Tohru Koma
A two-dimensional quantum Hall system is studied for a wide class of potentials including single-body random potentials and repulsive electron-electron interactions. We assume that…

Spectral Gaps of Quantum Hall Systems with Interactions
Tohru Koma
A two-dimensional quantum Hall system without disorder for a wide class of interactions including any two-body interaction with finite range is studied by using the Lieb-Schultz-Ma…

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…
