Abstract
In the last years, a new family of energy density functionals directly inspired by effective field theory (EFT) has been developed, among which the ELYO (extended Lee-Yang Orsay) functional. In this paper, a new extension of ELYO that includes the recently calculated fourth-order EFT terms is presented. Compared to the previous version, the description of neutron-drop energies slightly degrades for a harmonic trap ħω = 10 MeV—yet remaining reasonable—, but improves for ħω = 5 MeV. Furthermore, the obtained neutron effective mass agrees significantly better with ab-initio estimates.
