Our group have succeeded in generating quantum degenerate gases of ytterbium (Yb) atoms, which have two valence electrons, ahead of the world. Recently we are working on following topics:

1. SU(N) Hubbard model which has higher symmetric spin structure than those with electrons of spin 1/2.
2. Quantum many-body dynamics within unconventional optical lattice such as Lieb lattice or Plaquette lattice.
3. Nonequilibrium quantum dynamics.
4. Quantum many-body system with controlled dissipation and atom losses.
5. Topological quantum system such as thouless pumping.

We are also working verification experiments of standard model through high-resolution spectroscopy of isotope shift of atoms localized in an optical lattice.
