Effect of the iron valence in the two types of layers in LiFeOFeSe
Christoph Heil, Lilia Boeri, Heinrich Sormann +2
We perform electronic structure calculations for the recently synthesized iron-based superconductor LiFeOFeSe. In contrast to other iron-based superconductors, this mat…
Accurate bare susceptibilities from full-potential calculations
Christoph Heil, Heinrich Sormann, Lilia Boeri +2
Electronic susceptibilities are a very popular tool to study electronic and magnetic properties of materials, both in experiment and theory. Unfortunately, the numerical evaluation…
Indirect evidence for strong coupling superconductivity in FeSe under pressure from first-principle calculations
Christoph Heil, Markus Aichhorn, Heinrich Sormann +2
Whether the pairing mechanism for superconductivity in iron-based superconductors is of itinerant or local character is a question still debated on. In order to investigate the inf…
On the reliability of linear band structure methods
G. Kontrym-Sznajd, M. Samsel-Czekala, G. E. Grechnev +1
We discuss an efficiency of various band structure algorithms in determining the Fermi surface (FS) of the paramagnetic ErGa3. The linear muffin-tin orbital (LMTO) in the atomic sp…
Many-body effects observed in the positron annihilation experiment
G. Kontrym-Sznajd, H. Sormann
This paper is devoted to study many-body effects in the positron annihilation experiment, both electron-positron (e-p) and electron-electron (e-e) correlations. Various theories of…
Electron momentum density in yttrium
G. Kontrym-Sznajd, M. Samsel-Czekala, A. Pietraszko +7
A simultaneous analysis of high-resolution directional Compton profiles and two-dimensional angular correlation of positron annihilation experimental data has been performed by stu…
