Slide 2

The Nuclear Landscape The Nuclear Landscape and the Big Questions (National Academy Science report) How did matter come into being and how does it evolve? How does subatomic matter organize itself and what phenomena emerge? Are the fundamental interactions that are basic to the structure of matter fully understood? How can the knowledge and technological progress provided by nuclear physics best be used to benefit society?

Slide 3

Big science questions How did matter come into being and how does it evolve? Understanding the observed sequence of abundance enrichment of nuclides is a challenge to theory.

Slide 4

Enhancing the coupling between experiment and theory Theory can: assess the scientific impact of experiments help identify critical measurements evaluate whether anticipated experimental errors are sufficient for the goal interpret experimental results make sense of surprises we will find along the way provide input for planning experimental programs

Slide 5

Theory also need errors bars Develop Uncertainty Quantification for nuclear structure and reactions modern statistical tools for uncertainty quantification modern optimization tools multi-model surveys to assess systematic uncertainties An example with density functional theory: As one moves away from stability models diverge!

High Performance Computing Perpetuating the successes of the SciDAC projects UNEDF and NUCLEI demonstrate the powerful synergy of low- energy nuclear theory and high- performance computing Other partners: LQCD SciDAC, Astro SciDAC Additional resources through ASCR and NNSA High performance computing provides answers to questions that neither experiment nor analytic theory can address; hence, it becomes a third leg supporting the field of nuclear physics.

Education of next generation: Training in Advanced Low-Energy Nuclear Theory (TALENT) TALENT is an educational initiative in Europe and North America to provide advanced and comprehensive training to graduate students and young researchers (both theorists and experimentalists) in modern low-energy nuclear theory. Problem: Small numbers and distributed expertise preclude University groups from adequately educating young scientists in state-of-the-art nuclear theory Nine courses planned for 3-4 year cycle, ranging from nuclear forces to few- and many-body methods, to theory for experiments, astrophysics, and exotic nuclei, to high-performance computing. All but one course has run so far and some are preparing the second round. Organization and details at nucleartalent.org INT 2013 GANIL2013

FRIB theory center steering committee Constituted in Spring 2013 by NSCL director with the mandate to determine the required ingredients, including ramp-up funding options and an appropriate organizational structure for a future FRIB theory center, and then proceed to work with the agencies and develop a path forward.

Slide 14

Added value of the FRIB theory alliance The theory alliance: brings a focal point for stimulating continuous interactions with experiment can be a home for initiatives such as CUSTIPEN and FUSTIPEN serves as a partner for larger international collaborations The FRIB theory alliance: enables a prestigious national fellow program: enhances the visibility of the field and attracts the brightest young people emphasizes the importance of low-energy nuclear theory: enhances the opportunity to create permanent positions in nuclear theory fosters interdisciplinary collaborations coordinates an educational program in advanced nuclear theory brings multiple opportunities to leverage efforts and funding
