Short-range correlations in isospin symmetric and asymmetric nuclear matter: a microscopic perspective
Abstract
Short-range correlations in nuclear and neutron matter are examined through the properties of the correlated wave function obtained by solving the Bethe-Goldstone equation. Tensor correlations are explored through the dominant tensor-driven transition and central correlations through the singlet and triplet S waves. Predictions from a popular meson-theoretic nucleon-nucleon potential employed in the Dirac-Brueckner-Hartree-Fock approach are compared with those from two- and three-body high-quality chiral interactions in Brueckner G-matrix calculations. Short-range correlations in symmetric matter are remarkably stronger than in neutron matter. It is found that short-range correlations are very model dependent and have a large impact on the symmetry energy above normal density.
