Single-particle dynamics in the vicinity of the Mott-Hubbard metal-to-insulator transition
Micha{ \ l} Karski, Carsten Raas, and G\ " { o} tz S. Uhrig

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.
