Extended s-wave pairing originating from the $a_{1 g}$ band in Na $_{x}$ CoO $_{2} \cdot y$ H $_{2}$ O

Kazuhiko Kuroki, Seiichiro Onari, Yukio Tanaka +2

Motivated by recent experiments and band calculation results, we investigate the possibility of superconductivity originating from the $a_{1 g}$ band of Na $_{x}$ CoO $_{2} \cdot y$ H $_{2}$ O a…

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.…
