Lattice defects and boundaries in conducting carbon nanotubes
Sebastian A. Reyes, Alexander Struck, Sebastian Eggert
We consider the effect of various defects and boundary structures on the low energy electronic properties in conducting zigzag and armchair carbon nanotubes. The tight binding mode…
Conductance plateau transitions in quantum Hall wires with spatially correlated random magnetic fields
Tohru Kawarabayashi, Yoshiyuki Ono, Tomi Ohtsuki +3
Quantum transport properties in quantum Hall wires in the presence of spatially correlated disordered magnetic fields are investigated numerically. It is found that the correlation…
Unconventional conductance plateau transitions in quantum Hall wires with spatially correlated disorder
Tohru Kawarabayashi, Yoshiyuki Ono, Tomi Ohtsuki +3
Quantum transport properties in quantum Hall wires in the presence of spatially correlated random potential are investigated numerically. It is found that the potential correlation…
Electron correlations and single-particle physics in the Integer Quantum Hall Effect
Alexander Struck, Bernhard Kramer
The compressibility of a two-dimensional electron system with spin in a spatially correlated random potential and a quantizing magnetic field is investigated. Electron-electron int…
Nonchiral Edge States at the Chiral Metal Insulator Transition in Disordered Quantum Hall Wires
Alexander Struck, Bernhard Kramer, Tomi Ohtsuki +1
The quantum phase diagram of disordered wires in a strong magnetic field is studied as a function of wire width and energy. The two-terminal conductance shows zero-temperature disc…
