Stability of the compressible quantum Hall state around the half-filled Landau level
Kenzo Ishikawa, Nobuki Maeda, Tetsuyuki Ochiai
We study the compressible states in the quantum Hall system using a mean field theory on the von Neumann lattice. In the lowest Landau level, a kinetic energy is generated dynamica…
Quantum Hall Dynamics on von Neumann Lattice
K. Ishikawa, N. Maeda, T. Ochiai +1
Quantum Hall Dynamics is formulated on von Neumann lattice representation where electrons in Landau levels are defined on lattice sites and are treated systematically like lattice…
Theory of Current-Induced Breakdown of the Quantum Hall Effect
Kenzo Ishikawa, Nobuki Maeda, Tetsuyuki Ochiai +1
By studying the quantum Hall effect of stationary states with high values of injected current using a von Neumann lattice representation, we found that broadening of extended state…
