The Gamow shell model (GSM) framework is extended to the study of weakly bound hypernuclei. As an initial application, we investigate the neutron-rich He hyper-isotopes from Λ6He to Λ9He, accurately treating the unbound or loosely bound character of hypernuclear many-body states. The energy spectra,...
