Quantum Melting of Charge Order due to Frustration in Two-Dimensional Quarter-Filled Systems

Jaime Merino, Hitoshi Seo, Masao Ogata

The effect of geometrical frustration in a two-dimensional 1/4-filled strongly correlated electron system is studied theoretically, motivated by layered organic molecular crystals.…

Ferromagnetic fluctuation and possible triplet superconductivity in Na_xCoO_2*yH_2O: Fluctuation-exchange study of multi-orbital Hubbard model

Masahito Mochizuki, Youichi Yanase, Masao Ogata

Spin and charge fluctuations and superconductivity in a recently discovered superconductor Na_xCoO_2*yH_2O are studied based on a multi-orbital Hubbard model. Tight-binding paramet…
