    "abstract": "A multi-configuration mixing approach built on essentially complex,\nsymmetry-projected Hartree-Fock-Bogoliubov (HFB) mean fields is introduced. The\nmean fields are obtained by variation after projection. The configuration space\nconsists out of the symmetry-projected HFB vacuum and the symmetry-projected\ntwo-quasiparticle excitations for even, and the symmetry-projected\none-quasiparticle excitations for odd A systems. The underlying complex HFB\ntransformations are assumed to be time-reversal invariant and axially\nsymmetric. The model allows nuclear structure calculations in large model\nspaces with arbitrary two-body interactions. The approach has been applied to\n$^{20}$Ne and $^{22}$Ne. Good agreement with the exact shell model results and\nconsiderable improvement with respect to older calculations, in which only real\nHFB transformations were admitted, is obtained.",
