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…
Irreversibility from a Reversible Equation
Hiroshi Ezawa, Koichi Nakamura, Keiji Watanabe
After a discussion on the state of local equilibrium with temperature inhomogeneity, comparing mixture state reprsentation in statistical mechanics and pure state representation in…
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…
