Abstract

When viewed at frequencies below about 8 THz (250 cm^-1; 30 meV) the ab-plane optical conductivity of the cuprate superconductors (in their normal state) is well described by a Drude model. Examples include optimally-doped YBa₂Cu₃O_7-δ and Bi ₂Sr₂CaCu₂O₈ ; even the underdoped phases have a Drude character to their optical conductivity. A residual Drude-like normal fluid is seen in the superconducting state in most cases; the scattering rate of this quasiparticle contribution collapses at T_c.
