Density-matrix expansion for local three-nucleon interactions — •Lars Zurek^1,2, Arianna Carbone^1,2, Eduardo Antonio Coello Pérez^1,2, and Achim Schwenk^1,2,3 — ¹Institut für Kernphysik, Technische Universität Darmstadt — ²ExtreMe Matter Institute EMMI, GSI Helmholtzzentrum für Schwerionenforschung GmbH — ³Max-Planck-Institut für Kernphysik, Heidelberg

The Negele-Vautherin density-matrix expansion is applied to the Hartree-Fock energy due to three-nucleon interactions. Using the density-matrix expansion, off-diagonal density matrices can be rewritten in terms of local densities and their derivatives. The resulting approximations for the density matrices are applied to calculate the contributions to the Hartree-Fock energy due to different local three-nucleon interactions derived from chiral effective field theory and fit in recent quantum Monte-Carlo calculations. The resulting energy-density functionals are presented and compared to other results.
