Effects of Core-Hole Screening on Spin-Polarised Auger Spectra from Ferromagnetic Nickel
T. Wegner, M. Potthoff, W. Nolting
We calculate the spin- and temperature-dependent local density of states for ferromagnetic Ni in the presence of a core hole at a distinguished site in the lattice. Correlations am…

Theory of Spin-Resolved Auger-Electron Spectroscopy from Ferromagnetic 3d-Transition Metals
T. Wegner, M. Potthoff, W. Nolting
CVV Auger electron spectra are calculated for a multi-band Hubbard model including correlations among the valence electrons as well as correlations between core and valence electro…

The asymmetric single-impurity Anderson model - the modified perturbation theory
D. Meyer, T. Wegner, M. Potthoff +1
We investigate the single-impurity Anderson model by means of the recently introduced modified perturbation theory. This approximation scheme yields reasonable results away from th…
