Signatures of electronic correlations in half-metals — •Markus Dutschke1, Liviu Chioncel1,2, and Junya Otsuki1,31Theoretical Physics III, Center for Electronic Correlations and Magnetism, Institute of Physics, University of Augsburg, D-86135 Augsburg, Germany — 2Augsburg Center for Innovative Technologies, University of Augsburg, D-86135 Augsburg, Germany — 3Department of Physics, Tohoku University, Sendai 980-8578, Japan

The distinctive feature of the electronic correlations in half-metals is the existence of Non-quasiparticle states, within the half-metallic gap, predicted previously in model as well as realistic LDA+DMFT calculations. We revisit this problem considering a simplified Hubbard model solved in DMFT using the CT-QMC impurity solver. In the same time we present an implementation of the hybridization expansion quantum impurity solver, based on the segment representation.
