We have investigated the electronic properties of strongly correlated materials in the framework of the dynamical mean field theory(DMFT).
A first part of our work considers a possible disordered local moments phase by solving the DMFT with the iterated perturbation theory(IPT).
Secondly, we investigate the effect of a static diagonal disorder in the DMFT with an approach based on the non-crossing approximation and the coherent potential approximation.
Coherent and incoherent part of the densities of states are obtained by NCA.
