Observation of Two Cascading Screening Processes in an Iron-based Superconductor
Ming-Hua Chang, Steffen Backes, Donghui Lu +8
Understanding how renormalized quasiparticles emerge in strongly correlated electron materials provides a challenge for both experiment and theory. It has been predicted that disti…
Dispersion kinks from electronic correlations in an unconventional iron-based superconductor
Ming-Hua Chang, Steffen Backes, Donghui Lu +7
The attractive interaction in conventional BCS superconductors is provided by a bosonic mode. However, the pairing glue of most unconventional superconductors is unknown. The effec…
Diagnostics for plasmon satellites and Hubbard bands in transition metal oxides
Steffen Backes, Hong Jiang, Silke Biermann
Coulomb correlations between the electrons imprint characteristic signatures to the spectral properties of materials. Among others, they are at the origin of a rich phenomenology o…
Effect of non-local correlations on the electronic structure of LiFeAs
Karim Zantout, Steffen Backes, Roser Valentí
We investigate the role of non-local correlations in LiFeAs by exploring an ab-initio-derived multi-orbital Hubbard model for LiFeAs via the Two-Particle Self-Consistent (TPSC) app…
