Low-Energy Nuclear Physics National HPC Initiative: Building a Universal Nuclear Energy Density Functional
Researchers will arrive at a comprehensive and unified description of nuclei and their reactions that is grounded in the interactions between the constituent nucleons. Current phenomenological models of nuclear structure and reactions will be replaced with a well-founded microscopic theory delivering maximum predictive power with minimal, well quantified uncertainties. A national effort will link theoretical physics and computational science together to develop forefront software for state-of-the-art architectures. A national capability will be built to calculate nuclear structure and low-energy nuclear cross sections, and assess their uncertainties, relevant to several DOE programs. Nuclear structure and reactions play an essential role in the science to be investigated at the Rare Isotope Accelerator (RIA) and in nuclear physics applications to the Science-Based Stockpile Stewardship program, next generation reactors, and threat reduction. In order to build this capability, we will develop a multi-pronged program of theoretical, algorithmic, and computational developments that will deliver nuclear cross section information critical to DOE programs that is more accurate than is currently available. We anticipate an expansion of the computational techniques and methods we currently employ, and developments of new treatments, to take advantage of petascale architectures.
