Superconductivity in Na_xCoO_2yH_2O by charge fluctuation
Yasuhiro Tanaka, Youichi Yanase, Masao Ogata
A new mechanism for superconductivity in the newly discovered Co-based oxide is proposed by using charge fluctuation. A single-band extended Hubbard model on the triangular lattice…

Charge fluctuation induced superconducting state in two-dimensional quarter-filled electron systems
Akito Kobayashi, Yasuhiro Tanaka, Masao Ogata +1
We investigate the superconducting (SC) state in two-dimensional extended Hubbard model at a quarter-filling with the on-site repulsive interaction () and the nearest-neighbor o…
