Two currently funded international collaborative programs in nuclear theory:France-U.S. Theory Institute for Physics with Exotic Nuclei (FUSTIPEN)
(CUSTIPEN)
CUSTIPEN was officially launched on May 1, 2013 at Peking UniversityCUSTIPEN Governing Board Chinese Members:Yugang Ma (Shanghai Institute of Applied Physics)Zhongzhou Ren (Nanjing University)Furong Xu (Managing Director, Peking University)Yanlin Ye (Co-Director, Peking University)Wenlong Zhan (Chinese Academy of Science)Huanqiao Zhang (China Institute of Atomic Energy)Yuhu Zhang (Institute of Modern Physics, CAS)Shangui Zhou (Institute of Theoretical Physics, CAS)
U.S. Members:P. Danielewicz (Co-Director, Michigan State University)Bao-An Li (Principal Investigator, Texas A&M-Commerce)W. Nazarewicz (FRIB and Michigan State University) J. Piekarewicz (Florida State University)B. Sherrill (FRIB and Michigan State University).

Exotic Nuclei
Collaborations are essential to move forward!
The complexity of the new problems/challenges require varied expertise, theoretical tools, computing resources, minds, manpower and funding that are hard to find in a single country

CUSTIPEN’s objective: Providing theoretical support in combining American and Chinese nuclear forces to explore a rich menu of compelling science opportunities with exotic nuclei
• Both countries have invested heavily in radioactive beam facilities and experiments • Experiments in both countries need stronger theoretical supports
• China continuingly provides many high-quality Ph.D students and postdocs in nuclear physics to the USA, CUSTIPEN facilitates continued collaboration of Chinese oversea-returners and their US partners, thus enhance workforce mobility across the pacific ocean
• More students, postdocs and faculty members paid by China to work in the US, e.g., two nuclear theorists were paid by China Scholarship Council to work at TAMUC last year
• Better use of Chinese world-leading expertise in certain areas of nuclear theory in understanding US-Lab data: e.g., IQMD analysis of NSCL data on isospin diffusion by the CIAE group (Tsang et al., PRL); RMF analysis of ANL data on chiral doublet bands in 133Ce by the PKU group (Ayangeakaa et al. PRL), and vice versa, e.g., analyses of IMP data on the masses of exotic nuclei by H. Schatz and Alex Brown (Tu et al. PRL and Zhang et al. PRL)
• Making use of Chinese world-leading super-computing capabilities
Benefits to the US Nuclear Physics Programs--- making better use of Chinese expertise, funding, workforce and computing power
Achievements so far
Visits to CUSTIPEN by US-based scientists: 28 person-times during the first 2 years
Joint publications acknowledging DOE support for CUSTIPEN: 19 published, several under review and/or in preparation
Examples of joint projects:Adaptive multi-resolution 3D Hartree-Fock-Bogoliubov solver, odd-even mass staggering of Sn isotopes, Ab-initio calculations of nuclear structure, modern nuclear forces,nuclear symmetry energy, shear viscosity of neutron-rich matter,neutron-proton effective mass splitting in neutron-rich matter,neutron-skin of heavy nuclei, evaluation of nuclear data, EOS-gravity degeneracy in neutron stars…
