Progress toward building a quantum gas microscope for ytterbium atoms at KRISS

We report on the ongoing development of a quantum gas microscope apparatus for ytterbium atoms at KRISS. To detect individual atoms at a single-site resolution, we adopt the deep potential method, which does not require any cooling mechanism during the imaging process. The evaporatively cooled ytterbium atoms are repeatedly prepared in a single layer of an accordion lattice and adiabatically loaded in a 2D optical lattice. We illuminate the atoms using the laser detuned from the resonance, while the atoms are kept pinned in the lattice. The fluorescence emitted from the atoms is collected through a high NA imaging system, which is designed to have a long working distance. We expect an immediate extension to fermionic ytterbium isotopes and aim to explore rich physics such as SU(N) Fermi-Hubbard model and the Kondo problem in the near future.
