We discuss the GUDE functionals which consist of pion exchanges derived from chiral effective field theory and a Skyrme-like part. Certain pion terms lead to significant improvements in the description of ground-state energies, indicating they might be useful ingredients for true ab initio energy density functionals. In addition, we present estimates of the statistical parameter uncertainties of the GUDE functionals.

    A Hartree-Fock model with 11 chiral low-energy constants fitted to 18 nuclei reaches 3.5 MeV RMS on 107 even-even nuclei, worse than a liquid-drop fit to the same data.
