Unconventional superconducting pairing symmetry induced by phonons
I. Schnell, I. I. Mazin, Amy Y. Liu
The possibility of non-s-wave superconductivity induced by phonons is investigated using a simple model that is inspired by SrRuO. The model assumes a two-dimensional elect…
Unscreened Hartree-Fock calculations for metallic Fe, Co, Ni, and Cu from ab-initio Hamiltonians
I. Schnell, G. Czycholl, R. C. Albers
Unscreened Hartree-Fock approximation (HFA) calculations for metallic Fe, Co, Ni, and Cu are presented, by using a quantum-chemical approach. We believe that these are the first HF…
An ab-initio many-body method for electronic structure calculations of solids. II. Unscreened Hartree-Fock treatment for the 3d systems Fe, Co, Ni and Cu
I. Schnell, G. Czycholl, R. C. Albers
The ab-initio many-body method suggested in the preceding paper is applied to the 3d transition metals Fe, Co, Ni, and Cu. We use a linearized muffin-tin orbital calculation to det…
An ab-initio many-body method for electronic structure calculations of solids. I. Description of the method
I. Schnell, G. Czycholl, R. C. Albers
We propose a new, alternative method for ab-initio calculations of the electronic structure of solids, which has been specifically adapted to treat many-body effects in a more rigo…
Hubbard-U calculations for Cu from first-principles Wannier functions
I. schnell, G. Czycholl, R. C. Albers
We present first-principles calculations of optimally localized Wannier functions for Cu and use these for an ab-initio determination of Hubbard (Coulomb) matrix elements. We use a…
