Electron-Phonon mechanism for Superconductivity in NaCoO: Valence-Band Suhl-Kondo effect Driven by Shear Phonons
Keiji Yada, Hiroshi Kontani
To study the possible mechanism of superconductivity in NaCoO, we examine the interaction between all the relevant optical phonons (breathing and shear phonons) and $t…

Spin fluctuations and weak pseudogap behaviors in Na_{0.35}CoO_2:renomarization of band structure
Keiji Yada, Hiroshi Kontani
We analyze the normal electronic states of NaCoO based on the multi-orbital Hubbard model using the FLEX approximation. The fundamental electronic property of this sys…

Origin of the Weak Pseudo-gap Behaviors in Na_{0.35}CoO_2: Absence of Small Hole Pockets
Keiji Yada, Hiroshi Kontani
We analyze the ``normal electronic states'' of Na_{0.35}CoO_2 based on the effective d-p model with full d-orbital freedom using the fluctuation-exchange (FLEX) approximation. They…
