Neutron drops are a unique benchmark system to test nuclear interactions and constrain energy-density functionals, especially in the neutron-rich regime of the nuclear chart. We use the optimized effective potential method for the first time to second order 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.
