Theoretical ideas and experimental results concerning high-temperature superconductors
are reviewed. Special emphasis is given to calculations performed with the help of …

Although the vast majority of high-T c cuprate superconductors are hole-doped, a small
family of electron-doped compounds exists. Underinvestigated until recently, there has been …

Bulk-sensitive, polarization-dependent oxygen K-and copper L-edge absorption spectra of
single-domain La 2− x Sr x CuO 4 with CuO 2 planes tilted off the sample surface were …

We study the tJ and the Hubbard models at zero temperature using exact-diagonalization
techniques on√ 10×√ 10 and 4× 4 sites clusters. Quantum Monte Carlo simulation results …

O1s and Cu2p absorption edges of cuprate high-T c superconductors (HTSC) and related
compounds measured by electron energy-loss spectroscopy (EELS) and X-ray absorption …

The electronic structure of La x Sr 1− x TiO 3 has been studied by photoemission and x-ray
absorption spectroscopy. Electron do** through La substitution induces a new …

▪ Abstract Chemical analysis at high spatial resolution is the domain of analytical
transmission electron microscopy. Owing to rapid instrumental developments during the past …

Results of self-consistent linearized-augmented-plane-wave calculations within the local-
density-functional approximation (LDA) are presented of the electron-phonon-induced …

We demonstrate for the nearly half-filled Holstein-Hubbard model that the presence of
antiferomagnetic spin correlations can cause polaronic carrier self-localization, and hence a …

We report on the details of the insulator-metal transition (IMT) induced in Bi 2 Sr 2 (Ca z, R
1− z) Cu 2 O 8+ y (R= Y, Gd, Nd) by Ca 2+ do**. The resistivity in the insulating regime is …
