Abstract

The unusual quasilinear drop in the reflectivity as a function of frequency ω in YBa2Cu3O7 is explained in terms of Fermi surface nesting (nFL theory) accompanied by electron-electron scattering of intermediate strength. The Drude dielectric function acquires a calculated damping τnFL-1 = α Max (2T,|ωVBAR) and effective mass mnFL* (α,T,ω) which fit the reflectivity data well with α = 0.9 over a frequency range up to 8000 cm-1 (1 eV).
