A simple model of the strange-metal phase in cuprates
arXiv:2110.11762
Abstract
Hole doping of superconducting cuprates generates lattice defects of O atoms. At and beyond closing of the pseudogap, p =< p*, they form a highly symmetric superlattice. Umklapp processes involving reciprocal lattice vectors associated with both the host lattice and the O superlattice could account for the linear temperature dependence of resistivity.
