Intraband Optical Spectral Weight in the presence of a van Hove singularity: application to BiSrCaCuO
F. Marsiglio, F. Carbone, A. Kuzmenko +1
The Kubo single band sum rule is used to determine the optical spectral weight of a tight binding band with further than nearest neighbour hopping. We find for a wide range of para…
Doping Dependence of the Redistribution of Optical Spectral Weight in BiSrCaCuO
F. Carbone, A. B. Kuzmenko, H. J. A. Molegraaf +10
We present the ab-plane optical conductivity of four single crystals of BiSrCaCuO (Bi2212) with different carrier doping levels from the strongly underdop…
Scaling properties of the optical conductivity of Bi-based cuprates
D. van der Marel, F. Carbone, A. B. Kuzmenko +1
We present novel infrared optical conductivity data on the three layer high Tc superconductor Bi2Sr2Ca2Cu3O10 at optimal doping. We extend the analysis of an earlier publication, p…
In-plane optical spectral weight transfer in optimally doped BiSrCaCuO
F. Carbone, A. B. Kuzmenko, H. J. A. Molegraaf +3
We examine the redistribution of the in-plane optical spectral weight in the normal and superconducting state in tri-layer \bbb (Bi2223) near optimal doping ( = 110 K) on a si…
How strongly correlated is MnSi?
F. Carbone, M. Zangrando, A. Brinkman +7
We present an experimental study of the electronic structure of MnSi. Using X-ray Absorption Spectroscopy, X-ray photoemission and X-ray fluorescence we provide experimental eviden…
