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…
Berry's phase in the multimode Peierls states
Tohru Kawarabayashi, Yoshiyuki Ono, Chiduru Watanabe
It is shown that Berry's phase associated with the adiabatic change of local variables in the Hamiltonian can be used to characterize the multimode Peierls state, which has been pr…
Antiferromagnetic, Charge and Orbital Ordered States of Na0.5CoO2 Based on the Two-Dimensional Triangular Lattice d-p Model
Y. Yamakawa, Y. Ono
We investigate the electronic state of a CoO_2 plane in the layered cobalt oxides Na_xCoO_2 using the 11 band d-p model on a two-dimensional triangular lattice, where the tight-bin…
Electronic State of Na_xCoO_2 Based on the Two Dimensional Triangular Lattice d-p Model
Y. Yamakawa, Y. Ono
The electronic state in a CoO_2 plane of the layered cobalt oxides Na_{x}CoO_2 is investigated by using the 11 band d-p model on a two-dimensional triangular lattice, where the tig…
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…
Correlation Effect on the Two-Dimensional Peierls Phase
Shutaro Chiba, Yoshiyuki Ono
The effect of the electron-electron (e-e) interaction on the Peierls lattice distortions due to the electron-lattice (e-l) interaction is studied in the two-dimensional Peierls-Hub…
