Our method consists of two steps. First, the effective KS potential is determined from the ground-state density of a given system. Then, the knowledge of the potentials along a path in the space of densities is exploited in a line integration formula to determine numerically the KS energy of that system. A possible choice for the density path is proposed. A benchmark in the case of a simplified yet realistic nuclear system is shown to be successful, so the method seems promising for future applications.9 p.application/pdfeng(c) American Physical Society, 2022Teoria del funcional de densitatFísica nuclearEstructura nuclearDensity functionalsNuclear physicsNuclear structureinfo:eu-repo/semantics/article7452152024-10-18info:eu-repo/semantics/openAccess
