Doping and energy evolution of quasiparticle transport in cuprate superconductors with extended impurities

Within the nodal approximation of the quasiparticle excitations and scattering processes, we study the effect of the extended impurity scatterers on the quasiparticle transport of cuprate superconductors based on the framework of the kinetic energy driven superconducting mechanism. It is shown that there is a cusplike shape of the energy dependent microwave conductivity spectrum. In contrast with the dome shape of the doping dependent superconducting gap parameter, the minimum microwave conductivity occurs around the optimal doping, and then increases in both underdoped and overdoped regimes.
