Insulator-metal-insulator transition and selective spectral weight transfer in a disordered strongly correlated system
P. Lombardo, R. Hayn, G. I. Japaridze
We investigate the metal insulator transitions at finite temperature for the Hubbard model with diagonal alloy disorder. We solve the dynamical mean field theory equations with the…

Effect of Hund's exchange on the spectral function of a triply orbital degenerate correlated metal
P. Lombardo, A. - M. Daré, R. Hayn
We present an approach based on the dynamical mean field theory which is able to give the excitation spectrum of a triply degenerate Hubbard model with a Hund's exchange invariant…

Nearest neighbor exchange in Co- and Mn-doped ZnO
Thomas Chanier, M. Sargolzaei, I. Opahle +2
We calculate the magnetic interactions between two nearest neighbor substitutional magnetic ions (Co or Mn) in ZnO by means of density functional theory and compare it with the ava…
