Abstract

We present the first observation of a prominent quasiparticle peak in the photoemission spectrum of the metallic phase of [Formula presented] and report new spectral calculations that combine the local-density approximation with the dynamical mean-field theory (using quantum Monte Carlo simulations) to show the development of such a distinct peak with decreasing temperature. The experimental peak width and weight are significantly larger than in the theory.
