The one-step model of 2PPE applied to Co(001) — •Jürgen Braun1 and Hubert Ebert2 — 1Dept. Chemie, LMU München, Germany — 2Dept. Chemie, LMU München, Germany
Our 2PPE one-step model approach aims at a quantitative description of the time-dependent spectroscopic properties of specific solid systems under consideration, allowing for the inclusion of static correlation effects via the LSDA+DMFT electronic structure approach. To this end we follow Pendry’s one-step theory as close as possible and make extensive use of concepts of relativistic multiple-scattering theory within the LKKR method in order to guarantee for angular resolution in the spectroscopic calculations [1]. The fully relativistic formalism has been applied to fcc Co(001). We discuss our results in context with corresponding experimental data [2].
