Overview of physics topics, computational methods [configuration interaction (CI), quantum Monte-Carlo (QMC), and coupled-cluster (CC)], and employed codes that are part of this INCITE proposal “Ab-initio nuclear structure and nuclear reactions”. Complementary methods will be used to address physics topics that are relevant for various experimental facilities.

Project Summary

With this INCITE project, the researchers will lead to improvements in the simulation capabilities of atomic nuclei and nuclear matter, and their reactions with neutrinos and electrons.

Project Description

These team of researchers will advance their understanding of nuclear phenomena by targeting predictive capabilities regarding structure and reactions of nuclei, fundamental symmetries, and neutrino and electron interactions in nuclei. The project targets experiments and science at the Facility for Rare Isotope Beams (FRIB), Jefferson Laboratory (JLab), the Deep Underground Neutrino Experiment (DUNE), and ton-scale detectors for neutrinoless double β decay. The work will enable science not available previously and accelerate scientific discovery through high-performance computing. The team will perform state-of-the-art simulations to provide quantified predictions where direct experiment is not possible or is subject to large uncertainties. Such calculations are relevant to many applications in nuclear energy, nuclear security, and nuclear astrophysics, since rare nuclei lie at the heart of nucleosynthesis and energy generation in stars.
