Figure 1: Ground-state energies (left column) and excitation spectra (right column) of selected neon isotopes obtained with nonlocal chiral two plus three-nucleon interactions up to next-to-next-to-next-toleading order of the chiral expansion. The order-by-order dependence of observables is used to quantify the theory uncertainties resulting from the Hamiltonian (bars) and different model-space truncations are used to quantify the many-body uncertainties (bands).
