We construct semi-phenomenological nuclear energy-density functionals starting from conventional Skyrme functionals, here considered to represent short-range physics. Pion exchanges are added explicitly at the Hartree-Fock level by applying a density-matrix expansion to local interactions derived from chiral effective field theory. We determine energy-density functionals obtained in this fashion at different orders in the chiral expansion and investigate several choices in the density-matrix expansion.
