Coulomb repulsion and correlation strength in LaFeAsO from density functional and dynamical mean-field theories

Original language description

The role of electronic correlations in LaFeAsO is assessed using effective Hubbard Hamiltonian obtained from density functional calculations. It is shown that the on-site interaction parameters depend strongly on the choice of the single-particle Hilbertspace. Application of the dynamical mean-field theory to the effective Hamiltonian yields LaFeAsO moderately correlated.
