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…
Ab-initio study of the Coulomb interaction in NbxCo clusters: Strong on-site versus weak non-local screening
L. Peters, E. Sasioglu, I. Mertig +1
By means of ab-initio calculations in conjunction with the random-phase approximation (RPA) within the full-potential linearized augmented plane wave method we study the screening…
An ab-initio study of the electron-phonon coupling within a Cr(001)-surface
L. Peters, A. N. Rudenko, M. I. Katsnelson
It is experimentally well established that the Cr(001)-surface exhibits a sharp resonance around the Fermi level. However, there is no consensus about its physical origin. It is pr…
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…
