Project overview

We aim to construct a “unified platform for finite quantum many-body computation” based on the infinitesimally shifted Gaussian Lobe expansion method (GEM) proposed and developed by the project leader, and to describe the formation and evolution of matter in the universe from the fundamental particle level by using this platform. The goal is to obtain precise solutions for quantum many-body systems ranging from 3 to 100 particles by unifying GEM and other computational methods. Using this platform, we try to elucidate the internal materials of neutron stars and the interstellar molecular evolution process. We work on these issues in collaboration with experiments using the J-PARC accelerator and other facilities and with ultra-precise molecular spectroscopy experiments to determine heavy particle interactions and to verify the accuracy of calculations in order to improve the predictive power of calculations. We also collaborate with experiments on heavy-element nuclei to elucidate the heavy-element synthesis process in space. In addition, as a social contribution use of the unified platform, we support the development of RIKEN’s compact neutron source (RAMS).
