| Outline of Final Research Achievements |
Aiming at the development of new quantum state of matter where large-spin and multi-orbital degrees of freedom play an important role, we performed the experimental and theoretical studies using quantum gases of ytterbium atoms with SU(N=6) symmetry loaded in an optical lattice. As a result, we achieved the successful development of the experimental system for quantum simulator of the Kondo effect, realization of synthetic dimensional quantum transport, realization of a ultracold atomic mixture with large mass-imbalance, observation of SU(N) quantum magnetism and realization of lowest temperature for cold atom Fermi Hubbard model, observation of dissipation-induced change of quantum magnetism, creation of 4-body entangled state, real-time control of localization and delocalization and revealing the non-equilibrium correlation spreading, observation of disorder-induced localization and delocalization transition of Thouless pump.
