  Dynamical correlations and non-local contributions beyond static mean-field
theories are of fundamental importance for describing the electronic structure
of correlated metals. Their effects are usually described with many-body
approaches and non-local dynamical self-energies. We suggest here a class of
simple model self-energies that are a generalization of the static DFT +
Hubbard approach. This formulation, for simplicity called DFT+U({\omega})+V,
provides an intuitive physical picture, a lightweight implementation, and
displays very good agreement with experimental data.
