Neutron-rich nuclei offer an opportunity to investigate exotic nuclear structure phenomena and properties of the underlying nuclear forces. We present ab initio calculations for neutron-rich calcium isotopes, quantifying various sources of theoretical uncertainties. Based on these calculations we construct correlated mass models for different interactions from chiral effective field theory. Conditioning these models on experimentally known data, we make predictions for unknown two-neutron separation energies.
