An Assessment of U.S. Based Electron-Ion Collider Science, September 2018

The Committee on U.S.-Based Electron-Ion Collider Science Assessment was asked by the Department of Energy (DOE), in its statement of task, to assess the scientific justification for a U.S. domestic electron-ion collider (EIC) facility and to evaluate the importance and urgency of the science that an EIC would address to both nuclear science and the physical sciences more broadly. The committee’s task also included assessing the role of an EIC in the global context, including its relationship to other facilities within the United States and around the world. Lastly, the committee was asked to assess the broader impacts of an EIC, including on U.S. science leadership. The full statement of task is included in Appendix A.

In summary, the committee finds a compelling scientific case for such a facility. The science questions that an EIC will answer are central to completing an understanding of atoms as well as being integral to the agenda of nuclear physics today. In addition, the development of an EIC would advance accelerator science and technology in nuclear science; it would also benefit other fields of accelerator- based science and society, from medicine through materials science to elementary particle physics.

Quantum Computing for Theoretical Nuclear Physics, February 2018

Tremendous excitement exists among quantum computing enthusiasts as we witness the rapid evolution of quantum computing devices toward early practical implementation. Importantly, algorithm developments suggest that qubit devices have the potential to solve quantum many-body and quantum field theory problems of relevance to various research directions within the Department of Energy Office of Science and National Science Foundation. While exascale platforms represent the current horizon of excellence in computing, quantum computing provides the technology that lies beyond this horizon and opens the door to new vistas of theoretical endeavor. During a recent workshop at the Institute for Nuclear Theory, a group of 39 scientists from academia, government, national laboratories, and industry gathered to discuss the future of quantum computing for nuclear physics. Researchers described the basic scientific challenges in quantum chromodynamics and quantum many body problems that could be addressed utilizing the power of quantum computing in the future. The group also discussed mechanisms for developing quantum-computing algorithms specifically for nuclear physics applications. This White Paper provides a synopsis of the workshop discussions, and suggests possible activities that might be supported as part of a vibrant pilot program of nuclear physics research in this area.

NP Community Panel Report on Electron Ion Collider (EIC) Accelerator R&D, February 2017

An NP community panel, chaired by Dr. Kevin Jones of Oak Ridge National Laboratory, was charged by the Office of Nuclear Physics to provide guidance on the current status of accelerator R&D efforts and the priorities for future accelerator R&D that will enable an EIC pre-conceptual design. This design should deliver the EIC scientific objectives, while simultaneously minimizing technical risk and promoting cost effectiveness. This panel met on November 29-December 2, 2016 in the Washington DC area with presentations on the current EIC technical design concepts and R&D activities from the NP community. The report here describes the panel evaluation of the current status of accelerator R&D, proposed EIC concepts and their technical feasibility, and a list of R&D priorities for each EIC concept.

NP EXASCALE REQUIREMENTS REVIEW, JUNE 15–17, 2016

Imagine being able to predict — with unprecedented accuracy and precision — the structure of the proton and neutron, and the forces between them, directly from the dynamics of quarks and gluons, and then using this information in calculations of the structure and reactions of atomic nuclei and of the properties of dense neutron stars (NSs). Also imagine discovering new and exotic states of matter, and new laws of nature, by being able to collect more experimental data than we dream possible today, analyzing it in real time to feed back into an experiment, and curating the data with full tracking capabilities and with fully distributed data mining capabilities. Making this vision a reality would improve basic scientific understanding, enabling us to precisely calculate, for example, the spectrum of gravity waves emitted during NS coalescence, and would have important societal applications in nuclear energy research, stockpile stewardship, and other areas. This review presents the components and characteristics of the exascale computing ecosystems necessary to realize this vision.

Scientific Grand Challenges
January 26-28, 2009

Nuclear physics is manifested in areas as seemingly disparate as the history of the early universe, the generation of energy in the sun, and the creation of nearly all the elements in stellar furnaces and explosions.  A major focus of nuclear physics is the strong force and the atomic nuclei whose binding is a direct result of it, and whose stability underlies that of the atoms and thus molecules forming the familiar matter of all life forms and everyday objects.  The strong nuclear force is a complex one, much more so than the gravitational and electromagnetic forces familiar from daily life.  Understanding this nuclear force places particularly difficult demands not only on experiment but also on theory and calculation, particularly on computational power needed for these calculations.
