Coulomb correlations do not fill the e g hole pockets in Na0.3CoO2

There exists presently considerable debate over the question whether local Coulomb interactions can explain the absence of the small e g Fermi surface hole pockets in photoemission studies of Na0.3CoO2. By comparing dynamical mean field results for different single particle Hamiltonians and exact diagonalization as well as quantum Monte Carlo treatments, we show that, for realistic values of the Coulomb energy U and Hund exchange J, the e g pockets can be slightly enhanced or reduced compared to band structure predictions, but they do not disappear.

  23. M.D. Johannes (unpublished). In this context it is worthwhile to recall that truly intraplanar orbitals (i.e. dxy and $d_{x^2-y^2}$) have m=±2 quantum number and therefore give vanishing emission along the surface normal since the outgoing electron then has m=0 and the photon provides only Δm=±1 Google Scholar
