Outline of Final Research Achievements

In this research, Bose-Einstein condensed ytterbium atoms were loaded into a three-dimensional optical lattice and manipulated site-by-site using an optical magnetic resonance imaging. From spectra of ultra-narrow optical transitions, we directly observed the discretization of excitation energy of the atomic ensemble accompanied with the superfluid-to-Mott insulator transition. We also designed a quantum-gas microscope system, which can directly observe single atoms in each lattice sites, and establised its basic technique.
