Final Report Summary - ANSR (Ab initio approach to nuclear structure and reactions (++)) The ANSR project represents theoretical research on strongly-correlated many-particle systems. The main interest is in nuclear physics with microscopic studies of nuclear structure and reactions using realistic Hamiltonians. We have studied:1. Exotic nuclear systems The structure and reactions of atomic nuclei with extreme neutron to proton ratios have been studied using both ab initio many-body methods and halo effective field theory. A fascinating result is the microscopic desciption of clustering in nuclear halo systems. 2. Open quantum systemsAtomic and nuclear quantum systems at or above the breakup threshold have been described by including bound, resonant, and scattering states into our many-body basis. In particular, we have used the rigged Hilbert space formalism to study the tunneling of trapped ultracold atoms with a comparison to recent experiments in Heidelberg.3. General studies of strongly interacting many-body systems.We have adapted several methodologies from nuclear theory to study other strongly-interacting systems, such as bosonic and fermionic ultracold atoms in external traps.The ANSR project in numbers-----Number of peer-reviewed publications: 21 Number of invited talks: ~40Number of visiting scientists: ~20Research group:PI: Christian Forssén1 Professor Emeritus: Mikhail Zhukov1 Assistant professor: Lucas Platter (on leave of absence from 2012)1 Post doc: Jimmy Rotureau1 Research engineer: Håkan Johansson3 PhD Students: Daniel Sääf, Emil Ryberg, Boris Carlsson2 long-term visiting PhD students: Simon Tölle (Bonn University),Anton Gagin (St Petersburg State University) 5 Master students involved in the project36 Bachelor students involved in the project10 Research project assistants (master-level summer students working on research projects)(these people are, or have been, working directly on the ANSR project with funding from the ERC.)
