| Since the discovery of superconductivity in Fe pnictides in 2008, there has been an enourmous amount of theoretical and experimental work dedicated to the understanding of the behavior of these systems. In this talk I will concentrate on the importance of multiorbital, frustration and correlation effects and discuss within density functional theory (DFT) as well as a combination of density functional theory with dynamical mean field theory (LDA+DMFT) and model calculations the electronic and magnetic properties of a few families of Fe-based superconductors. |
