Theoretical models for exotic nuclei (2nd edition)

This article is a new edition of the review paper which we published in 2015 (Sagawa and Hagino in Eur Phys J A 51:102, 2015). We particularly summarize many developments in physics of exotic nuclei after we published the previous review article. This includes recent theoretical developments in the density functional theory, the three-body model, ab-initio approaches, and machine learnings, as well as new experimental findings such as tetra neutrons, knock-out reactions of halo nuclei, 4-neutron decays of \(^{28}\)O, the Coulomb breakup of \(^{19}\)B, and \(\beta \)-decays of nuclei relevant to r-process nucleosynthesis. We also cover halo and related topics in other disciplines, such as Efimov physics in cold atoms and halos in hypernuclei.
