Towards nuclear energy density functionals from first principles

Abstract

We discuss the GUDE functionals which consist of pion exchanges derived from chiral effective field theory and a Skyrme-like part. Certain pion terms lead to significant improvements in the description of ground-state energies, indicating they might be useful ingredients for true ab initio energy density functionals. In addition, we present estimates of the statistical parameter uncertainties of the GUDE functionals.
