Scaling of the superfluid density in high-temperature superconductors
C. C. Homes, S. V. Dordevic, T. Valla +1
A scaling relation ρ_s \simeq 35σ_{dc}T_c has been observed in the copper-oxide superconductors, where ρ_s is the strength of the superconducting condensate, T_c is the critical te…
Response to comment by Cuk et al
T. Valla, P. D. Johnson, Genda Gu +2
In a recent study of the optical conductivity of the Bi-2212 high temperature superconductor, Hwang, et al. have confirmed the mass-renormalization changes observed in ARPES but fi…
Quasi-Particle Spectra, Charge-Density-Wave, Superconductivity and Electron-Phonon Coupling in 2H-NbSe2
T. Valla, A. V. Fedorov, P. D. Johnson +5
High-resolution photoemission has been used to study the electronic structure of the charge density wave (CDW) and superconducting (SC) dichalcogenide, 2H- NbSe2. From the extracte…
On the Doping and Temperature Dependence of the Mass Enhancement Observed in the Cuprate Bi2212
P. D. Johnson, T. Valla, A. Fedorov +9
High-resolution photoemission is used to study the electronic structure of the cuprate superconductor, Bi2212, as a function of hole doping and temperature. A kink observed in the…
Charge-Density-Wave induced modifications to the quasiparticle self-energy in 2H TaSe2
T. Valla, A. V. Fedorov, P. D. Johnson +3
The self-energy of the photo-hole in 2H-TaSe2 is measured by angle-resolved photoemission spectroscopy (ARPES) as a function of binding energy and temperature. In the charge-densit…
Temperature Dependent Scattering Rates at the Fermi Surface of Optimally Doped Bi 2212
T. Valla, A. V. Fedorov, P. D. Johnson +3
For optimally doped Bi 2212, scattering rates in the normal state are found to have a linear temperature dependence over most of the Fermi surface. In the immediate vicinity of the…
