abstract

A detailed comparison of Faddeev and variational wave functions for $^3$H, calculated with realistic nuclear forces, has been made to study the form of three-body correlations in few-body nuclei. Three new three-body correlations for use in variational wave functions have been identified, which substantially reduce the difference with the Faddeev wave function. The difference between the variational upper bound and the Faddeev binding energy is reduced by half, to typically $<2\%$. These three-body correlations also produce a significant lowering of the variational binding energy for $^4$He and larger nuclei.

  1. On variational trial functions in the extended Thomas-Fermi method

    nucl-th 2024-11 accept novelty 6.0 of 10

    A kink in the trial nucleon density at the center of cylindrical or plane-parallel Wigner-Seitz cells makes the fourth-order extended Thomas-Fermi energy divergent; only spherical-cell kinks are harmless.
