摘　　要：Ab initio approaches are among the most advanced models to solve the nuclear many-body problem.In particular,the no-core-shell model and many-body perturbation theory have been recently extended to the Gamow shell model framework,where the harmonic oscillator basis is replaced by a basis bearing bound,resonance and scattering states,i.e.the Berggren basis.As continuum coupling is included at basis level and as configuration mixing takes care of internucleon correlations,halo and resonance nuclei can be properly described with the Gamow shell model.The development of the no-core Gamow shell model and the introduction of the■-box method in the Gamow shell model,as well as their first ab initio applications,will be reviewed in this paper.Peculiarities compared to models using harmonic oscillator bases will be shortly described.The current power and limitations of ab initio Gamow shell model will also be discussed,as well as its potential for future applications.
