What is the NUCLEI project?
The SciDAC-5 NUCLEI collaboration will perform research in computational low-energy nuclear physics and applied math/computer science that is relevant to DOE experimental facilities FRIB, ATLAS, and JLab and to future 1-ton scale neutrino experiments such as LEGEND. We seek more accurate and precise nuclear interactions and currents together with a more sophisticated quantification of uncertainties to make reliable predictions for stable nuclei and rare isotopes, the electroweak response of nuclei and nuclear matter, and nuclear fission.
We will research (i) properties and interactions of light nuclei and multinucleon systems; (ii) precision calculations of nuclear matrix elements for fundamental symmetries; (iii) neutrino and electron interactions in nuclei and dense matter; (iv) nuclear structure and properties of nuclei; and (v) nuclear fission. We will build upon our numerical solvers and computational libraries developed under previous SciDAC projects and capabilities in the SciDAC-5 Institutes. Applied mathematics and computer science research will be performed in the areas of algorithmic differentiation, eigensolvers, heterogeneous computing, machine learning, memory/concurrency management, numerical optimization, ordinary differential equations/linear solvers, performance optimization, statistical inference, and uncertainty quantification. We will employ existing and planned supercomputers at DOE's computing facilities.
