One-electron scattering rate and normal-state linear-T resistivity of the cuprates

الأصل · EN

Here we use a description of the electronic correlations contained in the Hubbard model on the square-lattice perturbed by very weak three-dimensional uniaxial anisotropy in terms of the residual interactions of charge c fermions and spin-neutral composite two-spinon s1 fermions. Excellent quantitative agreement with the anisotropic linear-ω one-electron scattering rate and normal-state linear-T resistivity observed in experiments on hole-doped cuprates with critical concentrations xc≈ 0.05 and x*≈ 0.27 is achieved. Our results provide strong evidence that the normal-state linear-T resistivity is a manifestation of low-temperature scale-invariant physics.
