Title: Extremely Correlated Fermi-Liquid Description of Normal-State ARPES in Cuprates

Abstract

The normal-state single particle spectral function of the high temperature superconducting cuprates, measured by the angle-resolved photoelectron spectroscopy (ARPES), has been considered both anomalous and crucial to understand. Here, we report an unprecedented success of the new extremely correlated Fermi liquid theory by one of us [B.S. Shastry Phys. Rev. Lett. 107 056403 (2011)] to describe both laser and conventional synchrotron ARPES data (nodal cut at optimal doping) on Bi{sub 2}Sr{sub 2}CaCu{sub 2}O{sub 8+{delta}} and synchrotron data on La{sub 1.85}Sr{sub 0.15}CuO{sub 4}. It fits all data sets with the same physical parameter values, satisfies the particle sum rule and successfully addresses two widely discussed kink anomalies in the dispersion.
