Asymmetric nuclear matter based on chiral effective field theory interactions — •Christian Drischler1,2, Vittorio Somà1,2, and Achim Schwenk2,1 — 1Institut für Kernphysik, Technische Universität Darmstadt, Germany — 2ExtreMe Matter Institute EMMI, GSI Helmholtzzentrum für Schwerionenforschung GmbH, Darmstadt, Germany
We investigate the properties of asymmetric nuclear matter with small proton fractions (high asymmetries). Our calculations are based on two- and three-nucleon forces from chiral effective field theory. We compare our microscopic results, including theoretical uncertainties, to a quasi-parabolic approximation developed to interpolate between pure neutron and symmetric nuclear matter. Our investigations are important for neutron-rich matter in astrophysics and as constraints for energy density functionals.
