Dual Boson approach with instantaneous interaction
L. Peters, E. G. C. P. van Loon, A. N. Rubtsov +3
The Dual Boson approach to strongly correlated systems generally involves a dynamic (frequency-dependent) interaction in the auxiliary impurity model. In this work, we explore the…
Quantum spin fluctuations and evolution of electronic structure in cuprates
E. A. Stepanov, L. Peters, I. S. Krivenko +3
Correlation effects in CuO layers give rise to a complicated landscape of collective excitations in high-T cuprates. Their description requires an accurate account fo…
Room temperature deformation in the FeMo -Phase
Sebastian Schröders, Stefanie Sandlöbes, Carola Birke +4
The role of TCP phases in deformation of superalloys and steels is still not fully resolved. In particular, the intrinsic deformation mechanisms of these phases are largely unknown…
On the origin of the quasi-particle peak in Cr(001) surfaces
L. Peters, D. Jacob, M. Karolak +2
In the spectral density of Cr(001) surfaces a sharp resonance close to the Fermi level is observed in both experiment and theory. For the physical origin of this peak two mechanism…
Magnetism and exchange interaction of small rare-earth clusters; Tb as a representative
Lars Peters, Saurabh Ghosh, Biplab Sanyal +9
Here we follow, both experimentally and theoretically, the development of magnetism in Tb clusters from the atomic limit, adding one atom at a time. The exchange interaction is, su…
The valence and spectral properties of rare-earth clusters
L. Peters, I. Di Marco, M. S. Litsarev +5
The rare-earths are known to have intriguing changes of the valence, depending on chemical surrounding or geometry. Here we make predictions from theory that combines density funct…
