performs \u00a0accurate calculations beyond the 10-body problem involving different particles with the \u201cInfinitesimally shifted \u00a0Gaussian Lobe expansion method (GEM)\u201d\u00a0 and developed by the project leader, which is the cornerstone of this research field.<\/li>\n\n\n\n<li>A01 group starts from the calculation of the boson 10-body problem and expands to the calculation of the Fermi 10-body problem and the 10-body problem including hetero particles.<\/li>\n\n\n\n<li>By giving information on \u00a0the binding energies and wavefunctions constructed by Group A01 to the group of large-scale shell model calculations and the group of density functional calculations, we aim to improve the accuracy of large-scale shell model calculations and density functional calculations, and to construct a platform for high-precision 100-body quantum many-body problem calculations.<\/li>\n\n\n\n<li>The group will apply this calculation method to the protonic molecule (Group B01) to elucidate the molecular structure of this molecule.<\/li>\n\n\n\n<li>In collaboration with the Hypernucleus Spectroscopy Experiment (Group B02), we will perform precise structure calculations of hypernuclei to determine the Baryon interactions\u00a0 and clarify the internal structure of neutron stars.<\/li>\n\n\n\n<li>A01 group contributes to industry-academia collaboration by calculating the nuclear reaction cross section required for RANS (Group B04).<\/li>\n<\/ul>\n","protected":false},"excerpt":{"rendered":"<p>A01\u201dChallenges in accurate calculation of quantum
