The role of Coulomb correlations in the iron pnictide LaFeAsO is studied by generalizing exact diagonalization dynamical mean field theory to five orbitals. For rotationally invariant Hund's rule coupling a transition from a paramagnetic Fermi-liquid phase to a non-Fermi-liquid metallic phase exhibiting frozen moments is found at moderate Coulomb energies. For Ising-like exchange, this transition occurs at a considerably lower critical Coulomb energy. The correlation-induced scattering rate as a function of doping relative to half-filling, i.e., δ = n/5 − 1, where n = 6 for the undoped material, is shown to be qualitatively similar to the one in the two-dimensional single-band Hubbard model which is commonly used to study strong correlations in high-Tc cuprates. In this scenario, the parent Mott insulator of LaFeAsO is the half-filled n = 5 limit, while the undoped n = 6 material corresponds to the critical doping region δc ≈ 0.2 in the cuprates, on the verge between the Fermi-liquid phase of the overdoped region and the non-Fermi-liquid pseudogap phase in the underdoped region.PACS. 71.20.Be Transition metals and alloys -71.27+a Strongly correlated electron systems
