Nuclear Matter Equation of State from Delta-full Chiral Interactions — •Yannick Dietz1,2, Jonas Keller1,2, Kai Hebeler1,2,3, and Achim Schwenk1,2,3 — 1Technische Universität Darmstadt, Department of Physics — 2ExtreMe Matter Institute EMMI, GSI Helmholtzzentrum für Schwerionenforschung GmbH — 3Max-Planck-Institut für Kernphysik, Heidelberg
We report results for infinite homogeneous nuclear matter calculations for the energy per particle and pressure at zero and finite temperature using Delta-full interactions based on chiral effective field theory. Our computations are carried out in many-body perturbation theory, where we include nucleon-nucleon and three-nucleon forces up to third order. Our results at zero temperature are consistent with previous studies of the equation of state based on Delta-less chiral potentials and lead to an improved convergence of uncertainty of the energy per particle.
