Title: Universal scaling of length, time, and energy for cuprate superconductors based on photoemission measurements of Bi 2 Sr 2 CaCu 2 O 8 + δ

Journal Article · · Physical Review. B, Condensed Matter and Materials Physics

A microscopic scaling relation linking the normal and superconducting states of the cuprates in the presence of a pseudogap is presented using angle-resolved photoemission spectroscopy. This scaling relation, complementary to the bulk universal scaling relation embodied by Homes’ law, explicitly connects the momentum-dependent amplitude of the d -wave superconducting order parameter at T ~ 0 to quasiparticle scattering mechanisms operative at T ≳ T c . The form of the scaling is proposed to be a consequence of the marginal Fermi-liquid phenomenology and the inherently strong dissipation of the normal pseudogap state of the cuprates.
