Edge states in graphene in magnetic fields -- a speciality of the edge mode embedded in the n=0 Landau band
Mitsuhiro Arikawa, Yasuhiro Hatsugai, Hideo Aoki
While usual edge states in the quantum Hall effect(QHE) reside between adjacent Landau levels, QHE in graphene has a peculiar edge mode at E=0 that reside right within the n=0 Land…
Accurate Model of a Vertical Pillar Quantum Dot
P. A. Maksym, Y. Nishi, D. G. Austing +4
An accurate model of a vertical pillar quantum dot is described. The full three dimensional structure of the device containing the dot is taken into account and this leads to an ef…
Unconventional pairing originating from disconnected Fermi surfaces in superconducting LaFeAsOF}
Kazuhiko Kuroki, Seiichiro Onari, Ryotaro Arita +4
For a newly discovered iron-based high superconductor LaFeAsOF, we have constructed a minimal model, where inclusion of all the five Fe bands is found to be n…
Phase diagram for the one-dimensional Hubbard-Holstein model: A density-matrix renormalization group study
Masaki Tezuka, Ryotaro Arita, Hideo Aoki
Phase diagram of the Hubbard-Holstein model in the coexistence of electron-electron and electron-phonon interactions has been theoretically obtained with the density-matrix renorma…
Flat-band ferromagnetism proposed for an organic polymer crystal
Ryotaro Arita, Yuji Suwa, Kazuhiko Kuroki +1
Motivated from the flat-band ferromagnetism conceived theoretically for a single chain of five membered rings (polyaminotriazole) by Arita {\it et al.}, [Phys. Rev. Lett. {\bf 88},…
Magnetic-field induced triplet superconductivity in the Hubbard model on a triangular lattice
Ryotaro Arita, Kazuhiko Kuroki, Hideo Aoki
We propose theoretically that a magnetic field can realize spin-triplet superconductivity in repulsively interacting electron systems having strong ferromagnetic spin fluctuations.…
