Phys. Rev. B 77, 075116 (2008) [20 pages]Single-particle dynamics in the vicinity of the Mott-Hubbard metal-to-insulator transitionReceived 11 October 2007; published 15 February 2008 The single-particle dynamics close to a metal-to-insulator transition induced by strong repulsive interaction between the electrons is investigated. The system is described by a half-filled Hubbard model which is treated by dynamic mean-field theory evaluated by high-resolution dynamic density-matrix renormalization. We provide theoretical spectra with momentum resolution which facilitate the comparison to photoelectron spectroscopy. © 2008 The American Physical Society URL:
