Infinite neutron matter is a unique benchmark system for testing chiral effective field theory iteractions since all many-body forces are predicted to N3LO. However, in finite nuclei shell and surface effects play an important role. These cannot be studied in infinite matter. Combining infinite neutron matter and neutron drops therefore provides important constraints for energy density functionals. For that we use the optimized effective potential method with local chiral interactions to calculate neutron drops in harmonic traps. Our calculations are a first step towards calculations of nuclei in ab initio density functional theory, which connects energy density functionals to chiral effective field theory interactions.
