International Collaborations in Nuclear Theory (ICNT)

Webpage for the ICNT workshop on "Physics of exotic nuclei: Theoretical advances and challenges", June 9-13, 2014, RIKEN Wako Campus, Tokyo, Japan.


Nuclear physics has an exciting future, highlighted in the low energy domain by the construction of the Radioactive Isotope Beam Factory (RIBF) in Japan, the Facility for Rare Ion Beams (FRIB) in the USA and the Facility for Antiproton and Ion Research (FAIR) in Germany. For a strong coupling of experiment and theory, RIKEN, NSCL/FRIB and GSI Helmholtzzentrum für Schwerionenforschung GmbH must serve as hubs to the theory community, fostering activity that is beneficial to the respective experimental programs. It is in this context that we have started a program for International Collaborations in Nuclear Theory in connection to rare isotopes (ICNT).

1.    Objectives

The main objective of this initiative is to stimulate and coordinate theory visitor efforts into topical programs that address specific needs of the rare isotope experimental activities at the three proposing institutions (RIKEN+CNS,NSCL/FRIB, GSI/FAIR). In addition, this program will organize sabbatical visits, aligning them with experimental priorities and coupling these long-term stays with topical programs when possible.

2.    Topical programs

The proposed topical programs will bring together 5-20 theorists for the duration of one month. During that period, these theorists will address a particular problem that is directly relevant to ongoing or future experimental programs in rare isotope science, and particularly important to the host laboratories (either RIKEN+CNS, NSCL/FRIB or GSI/FAIR). Most of the researcher’s time will be spent collaborating on the concerning issues, discussing the problem, elaborating strategies and developing solutions. A workshop can be attached to a topical program whenever that makes sense.  The topical program will have a practical outcome such that, at the end of the program, a deliverable must be made available (e.g. a code, a table with rates, a status report, etc). ICNT will cover local costs of participants.

Approved topical program for 2013:

3.    Sabbatical visits

Many theorists worldwide are still organized in small groups at various universities with no strong coupling to the leading laboratories. It is the role of the theory groups at the large laboratories to encourage sabbatical visits that can help to better align the efforts in an effective manner. ICNT will provide coordination and an international context for sabbatical visits. This will help the principal investigators to better understand the scientific needs of the various experimental programs and capitalize on their strengths. Whenever possible, topical programs will be organized in conjunction with the sabbatical visits.

4.    ICNT board

The ICNT board members are: B. Alex Brown (Chair, NSCL/FRIB), Hans Feldmeier (GSI), Bill Lynch (NSCL/FRIB), Taka Otsuka (U Tokyo), Marek Ploszajczak (GANIL), Hiroyoshi Sakurai (RIKEN) and Christoph Scheidenberger (GSI).

5.    Applications and program board

Applications for topical programs and/or sabbatical visits should be submitted to the Chair of the Board (email to

The proposal for topical programs should not exceed 3 pages and should contain a description of the scientific project, covering the scientific motivation, the relevance for the hosting laboratory, as well as the deliverables. It should also include the name and affiliations of critical experts that need to be present for the effort to be successful and their demonstrated interest in participating.

Application for sabbatical visits should include a CV of the applicant and a short narrative (up to 2 pages) describing the proposed work and its connection to the hosting laboratory as well as to a proposed topical program (if applicable).
