We examine short-range correlations in nuclear and neutron matter through the properties of the correlated wave function obtained by solving the Bethe-Goldstone equation. We explore tensor correlations through the dominant tensor-driven transition and central correlations through the singlet and triplet S waves. We compare predictions from a popular meson-theoretic nucleon- nucleon potential employed in the Dirac-Brueckner-Hartree-Fock approach 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. We find that short-range correlations are very model dependent and have a large impact on the symmetry energy above normal density.
