Superconductivity-Induced Transfer of In-Plane Spectral Weight in Bi2Sr2CaCu2O8: Resolving a Controversy
A. B. Kuzmenko, H. J. A. Molegraaf, F. Carbone +1
We present a detailed analysis of the superconductivity-induced redistribution of optical spectral weight in Bi2Sr2CaCu2O8 near optimal doping. It confirms the previous conclusion…
Ferromagnetism makes a doped semiconductor less shiny
F. P. Mena, J. F. DiTusa, D. van der Marel +5
Magnetic semiconductors have attracted interest because of the question of how a magnetic metal can be derived from a paramagnetic insulator. Here our approach is to carrier dope i…
Superconductivity by Kinetic Energy Saving?
D. van der Marel, H. J. A. Molegraaf, C. Presura +1
A brief introduction is given in the generic microscopic framework of superconductivity. The consequences for the temperature dependence of the kinetic energy, and the correlation…
Optical signatures of electron correlations in the cuprates
D. van der Marel
The f-sum rule is introduced and its applications to electronic and vibrational modes are discussed. A related integral over the intra-band part of sigma(omega) which is also valid…
Charge ordering signatures in the optical properties of beta-Na0.33V2O5
C. Presura, M. Popinciuc, P. H. M. van Loosdrecht +4
Temperature dependent optical spectra are reported for beta-Na0.33V2O5. The sodium ordering transition at T_Na = 240 K, and in particular the charge ordering transition at T_MI = 1…
