Observation of Hubbard Bands in -Manganese
S. Biermann, A. Dallmeyer, C. Carbone +5
We present angle-resolved photoemission spectra of the -phase of manganese as well as a theoretical analysis using a recently developed approach that combines density functional…
Quantum oscillations without quantum coherence
V. V. Dobrovitski, H. A. De Raedt, M. I. Katsnelson +1
We study numerically the damping of quantum oscillations and the increase of entropy with time in model spin systems decohered by a spin bath. In some experimentally relevant cases…
Magnetism of correlated systems: beyond LDA
A. I. Lichtenstein, M. I. Katsnelson
A novel approach to electronic correlations in magnetic crystals which takes into account a dynamical many-body effects is present. In order to to find a frequency dependence of th…
Finite-temperature magnetism of transition metals: an LDA+DMFT approach
A. I. Lichtenstein, M. I. Katsnelson, G. Kotliar
We present an ab initio quantum theory of the finite temperature magnetism of iron and nickel. A recently developed technique which combines dynamical mean-field theory with realis…
