Ab initio calculations for neutron drops are of interest for insights into neutron-rich nuclei and neutron star matter, and for examining the neutron-only sector of nucleon and 3-nucleon interactions. I present ab initio results calculated using the no-core shell model with 2- and 3-body chiral Hamiltonians for neutron drops with numbers N = 20-40 confined in a 10 MeV harmonic trap. I discuss ground state binding energies, radii, internal energies, and odd-even energy differences. Prior Green's Function Monte Carlo results using the Argonne v8' potential with added 3-nucleon forces serve as a comparison. I also present for comparison preliminary Hartree-Fock-Bogolyubov results using several energy density functionals.
