On the optical conductivity of Electron-Doped Cuprates I: Mott Physics
A. J. Millis, A. Zimmers, R. P. S. M. Lobo +1
The doping and temperature dependent conductivity of electron-doped cuprates is analysed. The variation of kinetic energy with doping is shown to imply that the materials are appro…
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…
