    "abstract": "We consider interacting Fermi systems close to the unitary regime and compute\nthe corrections to the energy density that are due to a large scattering length\nand a small effective range. Our approach exploits the universality of the\ndensity functional and determines the corrections from the analyical results\nfor the harmonically trapped two-body system. The corrections due to the finite\nscattering length compare well with the result of Monte Carlo simulations. We\nalso apply our results to symmetric neutron matter.",
