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…
Feshbach-Resonance-Enhanced Coherent Atom-Molecule Conversion with Ultra-Narrow Photoassociation Resonance
Shintaro Taie, Shunsuke Watanabe, Tomohiro Ichinose +1
We reveal the existence of high-density Feshbach resonances in the collision between the ground and metastable states of Yb and coherently produce the associated Feshbach m…
Topological Thouless Pumping of Ultracold Fermions
Shuta Nakajima, Takafumi Tomita, Shintaro Taie +5
A gas of electrons in a one-dimensional periodic potential can be transported even in the absence of a voltage bias if the potential is modulated slowly and periodically in time. R…
Coherent driving and freezing of bosonic matter wave in an optical Lieb lattice
Shintaro Taie, Hideki Ozawa, Tomohiro Ichinose +3
While kinetic energy of a massive particle generally has quadratic dependence on its momentum, a flat, dispersionless energy band is realized in crystals with specific lattice stru…
