Extracting the electron--boson spectral function F() from infrared and photoemission data using inverse theory
S. V. Dordevic, C. C. Homes, J. J. Tu +5
We present a new method of extracting electron-boson spectral function F() from infrared and photoemission data. This procedure is based on inverse theory and will be shown…
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…
Optical spectroscopy study on the electronic structure of
Jungho Kim, S. -J. Oh, Youngwoo Lee +4
The optical conductivity of EuCaB has been obtained from reflectivity and ellipsometry measurements for series of compositions, . The…
Infrared Properties of Electron Doped Cuprates: Tracking Normal State Gaps and Quantum Critical Behavior in Pr(2-x)Ce(x)CuO(4)
A. Zimmers, J. M. Tomczak, R. P. S. M. Lobo +7
We report the temperature dependence of the infrared-visible conductivity of Pr(2-x)Ce(x)CuO(4) thin films. When varying the doping from a non-superconducting film (x = 0.11) to a…
Infrared Signature of the Superconducting State in Pr(2-x)Ce(x)CuO(4)
A. Zimmers, R. P. S. M. Lobo, N. Bontemps +4
We measured the far infrared reflectivity of two superconducting Pr(2-x)Ce(x)CuO(4) films above and below Tc. The reflectivity in the superconducting state increases and the optica…
Optical properties of (Pr,Ce)2CuO4
A. Zimmers, N. Bontemps, R. P. S. M. Lobo +5
We studied the optical conductivity of electron doped Pr{1-x)Ce(x)CuO(4) from the underdoped to the overdoped regime. The observation of low to high frequency spectral weight trans…
