Phys. Rev. B 72, 224517 (2005) [13 pages]Mott physics and the optical conductivity of electron-doped cupratesReceived 5 November 2004; revised 5 October 2005; published 29 December 2005 The doping- and temperature-dependent conductivity of electron-doped cuprates is analyzed. The variation of kinetic energy with doping is shown to imply that the materials are approximately as strongly correlated as the hole-doped materials. The optical spectrum is fit to a quasiparticle scattering model; while the model fits the optical data well, factor of 3–4 inconsistencies with photoemission data are found, implying the presence of a large and doping-dependent Landau parameter. © 2005 The American Physical Society URL:
