High cutoffs in LO chiral EFT under Nogga-Timmermans-van Kolck power counting produce spurious bound states that prevent the Hartree-Fock method from yielding bound nuclear solutions without corrections beyond mean field.

Cutoff effects in Hartree-Fock calculations at leading order of chiral effective field theory
High cutoffs in LO chiral EFT under Nogga-Timmermans-van Kolck power counting produce spurious bound states that prevent the Hartree-Fock method from yielding bound nuclear solutions without corrections beyond mean field.
