| Research Abstract |
We successfully obtained quantum degeneracy mixture of Li and Yb by sympathetic evaporative cooling of Li by Yb. We developed three-dimensional optical lattice system whose wavelength was 1064nm, and observed lattice effects by loading LiYb quantum degenerate mixture. We proposed new control method of new atom-atom interaction by use of Feshbach resonance between Li in the ground state and Yb in metastable excited state, and confirmed our successfully excitation to the excited state of Yb atoms in three-dimensional optical lattce.
