Integer Quantum Hall Effect with Realistic Boundary Condition : Exact Quantization and Breakdown
K. Ishikawa, N. Maeda, K. Tadaki
A theory of integer quantum Hall effect(QHE) in realistic systems based on von Neumann lattice is presented. We show that the momentum representation is quite useful and that the q…

Is Hall Conductance in Hall Bar Geometry a Topological Invariant?
K. Ishikawa, N. Maeda, K. Tadaki
A deep connection between the Hall conductance in realistic situation and a topological invariant is pointed out based on von-Neumann lattice representation in which Landau level e…

Magnetic von-Neumann lattice for two-dimensional electrons in the magnetic field
K. Ishikawa, N. Maeda, K. Tadaki
One-particle eigenstates and eigenvalues of two-dimensional electrons in the strong magnetic field with short range impurity and impurities, cosine potential, boundary potential, a…
