Seminarium "Modeling of Complex Systems"

Modelling of isospin-symmetry-breaking (ISB) effects in atomic nuclei is a long-standing problem first tackled by Nolen and Schiffer in 1969. Since then, the interplay of electromagnetic and strong-force-rooted effects has been studied in many models. Our approach based on the Density Functional Theory (DFT) turns out to be very successful in this matter.During the seminar I will present how to reproduce binding energy differences of nuclei with N~Z in a broad range of masses (A=6-75) and what can we learn about the strong nuclear interaction using an effective theory. What is more, I will present calculations of nuclear structure and beta decay properties going beyond mean-field approximation.
