Simulating the nature of nuclei is a daunting task that requires a theory that can be applied to a wide variety of nuclei regardless of their quality. Dr. Gianluca Salvioni on theoretical nuclear physics studies, which builds such a theory by using precise first-principles calculation inputs from light nuclei. The nucleus is a valuable field for testing the fundamental forces of nature and a challenge for experimental and theoretical physics. Experimental facilities such as the Accelerator Laboratory at Jyvaskyla University.

It will be able to produce and measure radionuclides against the short-lived and exotic properties of these systems. We know that nucleus is formed by the interaction of nucleons (neutrons and protons) through so-called strong interactions. According to current understanding, these interactions have the characteristics of chiral effect interactions. Forces are derived from the symmetry of the basic components of nucleons, quarks, and gluons. The calculation of the ab initio method is based on the first principle, so that all nuclei are excited and interact with these chiral forces.

Due to the large amount of computing resources required, this calculation can only be performed on a limited number of light cores. In order to describe all of these methods, more approximations are needed, so the method based on the so-called density functional theory model is usually used instead of starting from scratch.

In the study, Salvioni derived kernel function parameters from the ab initio calculation of chiral interactions. In particular, he introduced perturbation into the ground state configuration of seven light nuclei and evaluated the functional parameter correlation from the response to the perturbation. These parameters were also used to test the properties of the infinite nuclear matter.
