Quantum-walk measurements with sequential imaging of the same atomic sample
Ryuta Yamamoto, Takeshi Fukuhara
We demonstrate sequential single-atom-resolved imaging of the same ultracold atomic sample and apply this technique to quantum-walk measurements in an optical lattice. In quantum g…
Observation of Chiral-Mode Domains in a Frustrated XY Model on Optical Triangular Lattices
Hideki Ozawa, Ryuta Yamamoto, Takeshi Fukuhara
We investigated the relaxation and excitation in a frustrated XY model realized by a Bose gas in Floquet-engineered optical triangular lattices. Periodically driving the position o…
Single-site-resolved imaging of ultracold atoms in a triangular optical lattice
Ryuta Yamamoto, Hideki Ozawa, David C. Nak +2
We demonstrate single-site-resolved fluorescence imaging of ultracold atoms in a triangular optical lattice by employing Raman sideband cooling. Combining a Rama…
Site-resolved imaging of single atoms with a Faraday quantum gas microscope
Ryuta Yamamoto, Jun Kobayashi, Kohei Kato +3
We successfully demonstrate a quantum gas microscopy using the Faraday effect which has an inherently non-destructive nature. The observed Faraday rotation angle reaches 3.0(2) deg…
An ytterbium quantum gas microscope with narrow-line laser cooling
Ryuta Yamamoto, Jun Kobayashi, Takuma Kuno +2
We demonstrate site-resolved imaging of individual bosonic atoms in a Hubbard-regime two-dimensional optical lattice with a short lattice constant of 266 nm. To…
Resonant Control of Interaction Between Different Electronic States
Shinya Kato, Seiji Sugawa, Kosuke Shibata +2
We observe a magnetic Feshbach resonance in a collision between the ground and metastable states of two-electron atoms of ytterbium (Yb). We measure the on-site interaction of doub…
