Observation of Hubbard Bands in $γ$-Manganese

Authors

Description

We present angle-resolved photoemission spectra of the $γ$-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 undispersive Hubbard bands in this system.
