Can Disorder Alone Destroy the eg′ Hole Pockets of NaxCoO2? A Wannier Function Based First-Principles Method for Disordered Systems
We investigate from first principles the proposed destruction of the controversial eg′ pockets in the Fermi surface of Na[subscript x]CoO[subscript 2] due to Na disorder, by calculating its k-dependent configuration-averaged spectral function ⟨A(k,ω)⟩. To this end, a Wannier function-based method is...
