Nesting, spin-fluctuations, and odd-gap superconductivity in NaxCoO2 yH2O

M. D. Johannes, I. I. Mazin, D. J. Singh +1

We have calculated the one-electron susceptibility of hydrated NaxCoO2 and find strong nesting nearly commensurate with a 2X2 superstructure. The nesting involves about 70% of all…
