Connecting Covariant Density Functional Theory to Microscopic Interactions

Within the field of effective field theory, there are many approaches which have become popular among many works. A predominant covariant effective field theory is relativistic mean-field theory which has been utilized in a number of different approaches related to the nuclear equation of state. Additionally, microscopic calculations have become possible with the increase in computational power as well as developments in field theory approaches. What remains however is that density functional theory provides a simpler approach to calculations of, for example, finite nuclei and the nuclear equation of state at different densities and proton-neutron asymmetries. For this reason, it is important to improve the reliability of density functional theory in capturing the behavior of nuclear systems. In this talk, we will show several relativistic interactions calibrated to calculations using chiral effective-field theory interactions and look for correlations and possible improvements to covariant density functional theory. By gaining insight into the properties not present in the current model, we show the areas in which additional terms or interactions may be added to the density functional to possibly capture missing behaviors.
