Optical and thermodynamic properties of the high-temperature superconductor HgBa_2CuO_4+delta
E. van Heumen, R. Lortz, A. B. Kuzmenko +9
In- and out-of-plane optical spectra and specific heat measurements for the single layer cuprate superconductor Hg-1201 at optimal doping (Tc = 97 K) are presented. Both the in-pla…
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…
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…
