Impurity-Scattering Assisted Umklapp Scattering as the Origin of Low-Temperature Resistivity in the Normal-State of Cuprate Superconductors
Impurity-assisted umklapp scattering off spin excitations explains T-quadratic resistivity below a doping-dependent scale in underdoped cuprates due to pseudogap-reduced spin density of states and T-linear resistivity above it in overdoped samples.
