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…
Stripe correlations in NaCoO
J. Geck, M. v. Zimmermann, H. Berger +5
We unambiguously demonstrate, based on high-energy x-ray diffraction data and LDA calculations, that sodium-density stripes are formed in Na0.75CoO2 at low temperatures and rule ou…
Analysis of possible field-induced superconductivity in anthracene, other polyacenes, and C60
S. -L. Drechsler, H. Rosner, G. Paasch +3
We consider electronic structure and superconductivity aspects in field-doped polyacenes (PA) and C60. Within a modified Thomas-Fermi approach for typical experimental values of th…
The upper critical field problem in MgB2
S. V. Shulga, S. -L. Drechsler, H. Eschrig +2
The upper critical field Hc2(T) for MgB2 is analyzed in terms of single and multi-band Eliashberg models. The relatively high value of Hc2(0) in the range of 14 to 18 Tesla can be…
