Overview of research goals, 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 achieve common research goals.

Project Summary

Building on previous INCITE research, this project employs advanced ab initio quantum many-body techniques coupled with applied mathematics and computer science methods to study a wide range of nuclei and to accurately describe the atomic nucleus from first principles.

Project Description

Atomic nuclei are strongly interacting, quantum many-body systems displaying fascinating properties. They exhibit emergent phenomena characteristic of large complex systems while at the same time being laboratories of most fundamental laws of nature. Predictions for the structure and reactions of nuclei, with assessed uncertainties, are important for the future of the nation’s energy and security needs.

Building on previous INCITE research, this project employs advanced ab initio quantum many-body techniques coupled with applied mathematics and computer science methods to study a wide range of nuclei and to accurately describe the atomic nucleus from first principles. The team’s predictions will complement DOE’s major investments in forefront experimental facilities, including existing low-energy nuclear physics facilities, Jefferson Laboratory, neutrino experiments, and the forthcoming Facility for Rare Isotope Beams (FRIB) under construction at Michigan State University. Ultimately, results from this INCITE project will help support and guide new experiments, explain observed phenomena, and potentially propel the discovery of new laws of nature.
