Phenomenological model for the normal state ARPES line shapes of high temperature superconductors

Abstract

Fully describing the single particle spectral function observed for high temperature superconduc- tors in the normal state is an important goal, yet unachieved. Here, we present a phenomenological model that demonstrates the capability to meet such a goal. The model results from employing key phenomenological improvement of the so-called extremely correlated Fermi liquid (ECFL) model, and is shown to successfully describe the data as a function of momentum as well as energy, for different materials (Bi2212 and LSCO), with an identical set of intrinsic parameters. This work goes well beyond the prevalent analysis of momentum dependent curves.
