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…
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…
Magnetic properties of Co doped Nb clusters
A. Diaz-Bachs, L. Peters, R. Logemann +4
From magnetic deflection experiments on isolated Co doped Nb clusters we made the interesting observation of some clusters being magnetic, while others appear to be non-magnetic. T…
Nonconventional screening of the Coulomb interaction in FexOy clusters: An ab-initio study
L. Peters, E. Sasioglu, S. Rossen +3
From microscopic point-dipole model calculations of the screening of the Coulomb interaction in non-polar systems by polarizable atoms, it is known that screening strongly depends…
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…
Treatment of 4f states of the rare-earths: the case study of TbN
L. Peters, I. Di Marco, P. Thunström +3
The lattice constant, bulk modulus and shear constant of TbN are calculated by means of density functional theory (DFT) in the local density approximation (LDA) and generalized gra…
Local structure in Ag[Co(CN)]: Colossal thermal expansion, rigid unit modes and argentophilic interactions
Michael J. Conterio, Andrew L. Goodwin, Matthew G. Tucker +4
Local structure in the colossal thermal expansion material Ag[Co(CN)] is studied here using a combination of neutron total scattering and reverse Monte Carlo (RMC) analysis…
