                      Effective Field Theory suffer from sign oscillations to a
                      varying degree dependent on the number of protons and
                      neutrons. Hence, such studies have hitherto been
                      concentrated on nuclei with equal numbers of protons and
                      neutrons, and especially on the alpha nuclei where the sign
                      oscillations are smallest. Here, we introduce the
                      'symmetry-sign extrapolation' method, which allows us to use
                      the approximate Wigner SU(4) symmetry of the nuclear
                      interaction to systematically extend the Projection Monte
                      Carlo calculations to nuclear systems where the sign problem
                      is severe. We benchmark this method by calculating the
                      ground-state energies of the $^{12}$C, $^6$He and $^6$Be
                      nuclei, and discuss its potential for studies of
                      neutron-rich halo nuclei and asymmetric nuclear matter.},
