Electron-Phonon mechanism for Superconductivity in Na $_{0.35}$ CoO $_{2}$ : Valence-Band Suhl-Kondo effect Driven by Shear Phonons

Keiji Yada, Hiroshi Kontani

To study the possible mechanism of superconductivity in Na $_{0.35}$ CoO $_{2}$ , 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 Na $_{0.35}$ CoO $_{2}$ 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…
