High multipole transitions in NIXS: valence and hybridization in 4f systems
R. A. Gordon, G. T. Seidler, T. T. Fister +4
Momentum-transfer (q) dependent non-resonant inelastic x-ray scattering measurements were made at the N4,5 edges for several rare earth compounds. With increasing q, giant dipole r…
Anisotropies in insulating LaSrCuO: angular resolved photoemission and optical absorption
O. P. Sushkov, Wenhui Xie, O. Jepsen +2
Due to the orthorhombic distortion of the lattice, the electronic hopping integrals along the and diagonals, the orthorhombic directions, are slightly different. We calcula…
Two Gaps Make a High Temperature Superconductor?
S. Huefner, M. A. Hossain, A. Damascelli +1
One of the keys to the high-temperature superconductivity puzzle is the identification of the energy scales associated with the emergence of a coherent condensate of superconductin…
Fermi pockets and correlation effects in underdoped YBa2Cu3O6.5
I. S. Elfimov, G. A. Sawatzky, A. Damascelli
The detection of quantum oscillations in the electrical resistivity of YBa2Cu3O6.5 provides direct evidence for the existence of Fermi surface pockets in an underdoped cuprate. We…
Non-resonant inelastic x-ray scattering involving excitonic excitations
M. W. Haverkort, A. Tanaka, L. H. Tjeng +1
In a recent publication Larson \textit{et al.} reported remarkably clear - excitations for NiO and CoO measured with x-ray energies well below the transition metal edge.…
Origin of charge density wave in the coupled spin ladders in SrCaCuO
Krzysztof Wohlfeld, Andrzej M. Oles, George A. Sawatzky
We formulate a d-p multiband charge transfer model for CuO coupled spin ladders, relevant for CuO plane of SrCaCuO, and solve it using Ha…
