Nuclear Structure And Processes In The Relativistic Nuclear Energy Density Functional Theory

Complete understanding of how stellar evolution and nucleosynthesis work, with self-consistent microscopic description of all relevant
nuclear properties and phenomena included, has not been achieved yet. In particular, weak-interaction processes play a crucial role in the late stages of the evolution of a massive star and in presupernova stellar collapse, as well as in the synthesis of elements in the universe.  In order to provide a theoretical description of relevant nuclear properties and processes, a theory framework of the relativistic nuclear energy density functional (RNEDF) has been established including the relativistic Hartree-Bogoliubov model and relativistic quasiparticle random phase approximation, supplemented with modeling of the cross sections and rates of the weak interaction processes. Recent implementations of the RNEDF provide a unified description of a variety of nuclear properties of astrophysical relevance, including the equation of state, nuclear masses, collective excitations and weak interaction processes such as electron capture and neutrino induced reactions.
