Influence of electronic correlations on orbital polarizations in the parent and doped iron pnictides
Influence of electronic correlations on orbital polarizations in the parent and doped iron pnictides
Orbital polarization and electronic correlation are two essential aspects in understanding the normal state and superconducting properties of multiorbital FeAs-based superconductors.In this Letter, we present a systematical study on the orbital polarization of iron pnictides from weak to strong Coulomb correlations within the KRSB approach.The magnetic phase diagram of the …
