Skyrme-quark-meson-coupling energy density functional predictions to nuclear ground state properties
Abstract
We present a systematic study of nuclear ground-state properties obtained with the Skyrme quark-meson coupling (SQMC) energy density functional and compare them with results from the SLy4d Skyrme parameterisation. The SQMC functional is constructed using the quark-meson coupling (QMC) model, which incorporates the internal quark structure of the nucleon and results in a significant reduction in the number of free parameters. We investigate binding energies, two-nucleon separation energies, charge radii, and quadrupole deformations across a broad range of nuclei. Particular attention is devoted to the isovector dependence of the spin-orbit interaction derived within the QMC model, and its impact on the binding energies of neutron-rich nuclei relevant to the r-process. We find that the SQMC functional provides a reasonable description of nuclear ground-state properties in comparison with SLy4d.
