2023DU01 Eur.Phys.J. A 59, 13 (2023) T.Duguet, J.-P.Ebran, M.Frosini, H.Hergert, V.Soma Rooting the EDF method into the ab initio framework PGCM-PT formalism based on MR-IMSRG pre-processed Hamiltonians NUCLEAR STRUCTURE 20Ne; calculated energy levels, J, π using the empirical nuclear energy density functional (EDF) method rooted into the recently formulated ab initio many-body perturbation theory built on top of the projected generator coordinate method (PGCM-PT), whenever the latter employs an effective Hamiltonian resulting from a multi-reference in-medium similarity renormalization group (MR-IMSRG) transformation of the nuclear Hamiltonian at play in chiral effective field theory. Comparison with available data.
