Energy density functionals from local chiral interactions — •Lars Zurek1,2, Eduardo Antonio Coello Pérez1,2, and Achim Schwenk1,2,31Institut für Kernphysik, Technische Universität Darmstadt — 2ExtreMe Matter Institute EMMI, GSI Helmholtzzentrum für Schwerionenforschung GmbH — 3Max-Planck-Institut für Kernphysik, Heidelberg

We employ the density-matrix expansion introduced by Negele and Vautherin and further developed by Gebremariam et al. in order to rewrite off-diagonal density matrices in terms of local densities and their derivatives. The resulting approximations for the density matrices are applied to calculate the energy density functionals arising from the contributions to the Hartree-Fock energy due to different local two- and three-nucleon interactions which were derived from chiral effective field theory and fit in recent calculations. The resulting energy-density functionals and their results for energies are presented and compared to other calculations.
