Abstract
We report measurements of anomalously large dissipative conductivities, σ1, in Bi2Sr2CaCu2O8+δ at low temperatures. We have measured the complex conductivity of Bi2Sr2CaCu2O8+δ thin films at 100-600 GHz as a function of doping from the underdoped to the overdoped state. At low temperatures there exists a residual σ1 which scales with the T = 0 superfluid density as the doping is varied. This residual σ1 is larger than the possible contribution to σ1 from a thermal population of quasiparticles (QP) at the d-wave gap nodes.
