We predict the limits of existence of atomic nuclei, the proton and neutron drip lines, from the light through medium-mass regions. Starting from a chiral two- and three-nucleon interaction with good saturation properties, we use the valence-space in-medium similarity renormalization group to calculate ground-state and separation energies from helium to iron, nearly 700 isotopes in total. We use the available experimental data to quantify the theoretical uncertainties for our ab initio calculations towards the drip lines. Where the drip lines are known experimentally, our predictions are consistent within the estimated uncertainty. For the neutron-rich sodium to chromium isotopes, we provide predictions to be tested at rare-isotope beam facilities.

Lattice calculation of the Sn isotopes near the proton dripline
First high-fidelity lattice calculations of 99-102Sn reach percent-level agreement with measured binding energies, confirm the N=50 shell closure, and find 99Sn less bound than extrapolations from heavier tin isotopes.

Imaging two-body correlations in atomic nuclei via low- and high-energy processes
Ground-state two-body correlations in light nuclei are better probed by high-energy eccentricity variances than by low-energy Kumar operators, whose deformation interpretation is shown to fail.

Constraining Hamiltonians from chiral effective field theory with neutron-star data
Neutron-star data, run through fast emulators, directly constrain the six two-nucleon low-energy constants of an N2LO chiral Hamiltonian, with future detectors able to strongly pin down the 3P1 channel.

From bare two-nucleon interaction to nuclear matter and finite nuclei in a relativistic framework
A leading-order relativistic chiral two-nucleon force, with four constants fit to scattering data, describes nuclear matter saturation and medium-mass nuclei binding energies and radii without three-nucleon forces.
