Abstract
We compute the structure of the exotic even nuclei Ne and Mg using interactions from chiral effective field theory (EFT). Our results for the ground-state rotational bands in Ne and Mg agree with data. We predict a well-deformed Ne and find that Mg exhibits an oblate deformed band close to the prolate ground-state, indicating the emergence of shape co-existence at the neutron dripline. A global sensitivity analysis shows that the subleading singlet -wave contact and a pion-nucleon coupling strongly impact deformation in chiral EFT.
