  "abstract": "We present the first application of the newly developed theory of effective nucleon-nucleon interactions to the structure of exotic nuclei. This theory, a novel revision of many-body perturbation theory, enables us to perform shell-model calculations with several major shells ({\\it e.g.} $sd$+$pf$). Using the Entem-Machleidt QCD-based $\\chi\\mathrm{N}^3\\mathrm{LO}$ interaction and the Fujita-Miyazawa three-body force, exotic neutron-rich Ne, Mg and Si isotopes are studied systematically, with a good description of ground-state energies, 2$_1^+$ and 4$_1^+$ levels, and E2 transitions, as the first shell-model calculation for the \"island of inversion\" without two-body matrix elements fitted to experiment. The drip lines are predicted. We show effective single-particle energies from this interaction, exhibiting the shell evolution produced by the $\\chi\\mathrm{N}^3\\mathrm{LO}$ interaction + three-body force. The doubly-magic structure of ${}^{34}\\mathrm{Si}$ is demonstrated.",
