    "abstract": "The density matrix renormalization group (DMRG) approach is extended to\ncomplex-symmetric density matrices characteristic of many-body open quantum\nsystems. Within the continuum shell model, we investigate the interplay between\nmany-body configuration interaction and coupling to open channels. It is shown\nthat the DMRG technique applied to broad resonances in the unbound neutron-rich\nnucleus 7He provides a highly accurate treatment of the coupling to the\nnon-resonant scattering continuum.",
