Recent progress in the studies of neutron rich and high-$Z$ systems within the covariant density functional theory

TL;DR

This paper reviews recent advances in covariant density functional theory applied to neutron-rich and superheavy nuclei, focusing on uncertainties in ground state properties and fission barriers.

Contribution

It provides a systematic analysis of uncertainties in modeling neutron-rich and superheavy nuclei within covariant density functional theory.

Findings

Uncertainty propagation affects predictions of nuclear properties.

Fission barrier descriptions vary with neutron richness.

Ground state properties are sensitive to model assumptions.

Abstract

The analysis of statistical and systematic uncertainties and their propogation to nuclear extremes has been performed. Two extremes of nuclear landscape (neutron-rich nuclei and superheavy nuclei) have been investigated. For the first extreme, we focus on the ground state properties. For the second extreme, we pay a particular attention to theoretical uncertainties in the description of fission barriers of superheavy nuclei and their evolution on going to neutron-rich nuclei.
