The authors demonstrate that the proposed framework of eigenvector continuation can robustly recover exact values of nuclear observables from a formally divergent low-order perturbative expansion without requiring any analytic knowledge of the expansion. The results illustrate that eigenvector continuation provides an efficient and powerful tool applicable to strongly interacting systems.
