| Outline of Final Research Achievements |
By using ultracold ytterbium atoms in an optical lattice which is a periodic potential, we could perform quantum simulation of quantum many-body system and contributed better understanding of quantum condensed matter. In particular, we achieved the following attainments like realization of topological Thouless pump, enhanced anti-ferromagnetic spin correlation in a SU(4) system, revealing the non-trivial effect of dissipation on the superfluid-Mott insulator transition, realization of Lieb optical lattice and observation of novel behavior of atoms in a flat band, revealing a new experimental platform suitable for the study of Kondo effect, development of a new method of quantum gas microscope, and the advanced theories related with the above topics.
