Structure and transport in multi-orbital Kondo systems
J. Kroha, S. Kirchner, G. Sellier +5
We consider Kondo impurity systems with multiple local orbitals, such as rare earth ions in a metallic host or multi--level quantum dots coupled to metallic leads. It is shown that…
High Resolution Photoemission Study on Low-T_K Ce Systems: Kondo Resonance, Crystal Field Structures, and their Temperature Dependence
D. Ehm, S. H"ufner, F. Reinert +5
We present a high-resolution photoemission study on the strongly correlated Ce-compounds CeCu_6, CeCu_2Si_2, CeRu_2Si_2, CeNi_2Ge_2, and CeSi_2. Using a normalization procedure bas…
Electron-phonon coupling and its evidence in the photoemission spectra of lead
F. Reinert, B. Eltner, G. Nicolay +3
We present a detailed study on the influence of strong electron-phonon coupling to the photoemission spectra of lead. Representing the strong-coupling regime of superconductivity,…
Atomic correlations in itinerant ferromagnets: quasi-particle bands of nickel
J. Buenemann, F. Gebhard, T. Ohm +11
We measure the band structure of nickel along various high-symmetry lines of the bulk Brillouin zone with angle-resolved photoelectron spectroscopy. The Gutzwiller theory for a nin…
Temperature dependence of the Kondo resonance and its satellites in CeCu_2Si_2
F. Reinert, D. Ehm, S. Schmidt +5
We present high-resolution photoemission spectroscopy studies on the Kondo resonance of the strongly-correlated Ce system CeCuSi. Exploiting the thermal broadening of the F…
