Temperature dependent optical conductivity of undoped cuprates with weak exchange
J. Malek, S. -L. Drechsler, U. Nitzsche +2
The optical conductivity sigma(omega) is calculated at finite temperature T for CuO_2 chain clusters within a pd-Hubbard model. Data at T = 300 K for Li_2CuO_2 are reanalyzed withi…
On the electronic structure of electron doped LaOFeAs as seen by X-ray absorption spectroscopy
T. Kroll, S. Bonhommeau, T. Kachel +14
We investigated the recently found superconductor LaO_{1-x}F_xFeAs by X-ray absorption spectroscopy (XAS). From a comparison of the O K-edge with LDA calculations we find good agre…
Valence band and core level photoemission spectros-copy of LaFeAsOF
A. Koitzsch, D. Inosov, J. Fink +9
We have investigated the electronic structure of LaFeAsOF (x = 0; 0.1; 0.2) by angle-integrated photoemission spectroscopy and local density approximation (LDA) based…
Strong electron-phonon coupling of the Fe breathing mode of LaO_{1-x}F_xFeAs
Helmut Eschrig
The electron-phonon coupling of LaOFFeAs is re-investigated on the basis of density functional theory in local density approximation. The implications of the ne…
Transition metal dimers as potential molecular magnets: A challenge to computational chemistry
Daniel Fritsch, Klaus Koepernik, Manuel Richter +1
Dimers are the smallest chemical objects that show magnetic anisotropy. We focus on 3 and 4 transition metal dimers that have magnetic ground states in most cases. Some of th…
