Description

Our understanding of the origin of elements heavier than iron relies on nucleosynthesis simulations, which in turn require accurate nuclear structure input, as beta-decay strengths and half-lives, especially for nuclei near the neutron dripline. In this talk, I will present preliminary coupled-cluster calculations of beta-decay strengths for neutron-rich nickel isotopes, motivated by future measurements planned at FRIB. I will also discuss recent theoretical developments enabling us to incorporate time dependence into our ab initio framework, with the long-term goal of achieving a real-time description of dynamical processes relevant for nucleosynthesis.
