We present angle-resolved photoemission spectra of the ³ phase of manganese as well as a theoretical analysis using a recently developed approach that combines density functional and dynamical mean-field methods (LDA + DMFT). The comparison of experimental data and theoretical predictions allows us to identify effects of the Coulomb correlations, namely, the presence of broad and nondispersive Hubbard bands in this system.

Abstract
We present angle-resolved photoemission spectra of the ³ phase of manganese as well as a theoretical analysis using a recently developed approach that combines density functional and dynamical mean-field methods (LDA + DMFT). The comparison of experimental data and theoretical predictions allows us to identify effects of the Coulomb correlations, namely, the presence of broad and nondispersive Hubbard bands in this system.File in questo prodotto:
