Abstract

Based on local density approximation plus dynamical mean-field theory (LDA+DMFT) calculations, we revisit the long-standing quasiparticle band narrowing problem of sodium metal. Using an on-site Coulomb interaction U derived from angle-resolved photoemission spectroscopy mass enhancement, we can describe various properties of this weakly correlated electron system. Intrinsic self-energy corrections lead to a Landau-Fermi liquid state with many-particle coherence and dynamical spectral weight transfer relevant to electronic structure and scattering rates of alkali metals.
