Abstract
We use angle-resolved photoemission to map the Fermi surface and quasiparticle dispersion of bulklike thin films of grown by pulsed laser deposition. The electronic self-energy deduced from our data reveals weak to moderate correlations in , consistent with our observation of well-defined electronic states over the entire occupied bandwidth. We further introduce spectral function calculations that combine dynamical mean-field theory with an unfolding procedure of density functional calculations and demonstrate good agreement of this approach with our experiments.
