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…
Observation of a p-wave Optical Feshbach Resonance
Rekishu Yamazaki, Shintaro Taie, Seiji Sugawa +2
We demonstrate a p$-wave optical Feshbach resonance (OFR) using purely long-range molecular states of a fermionic isotope of ytterbium ^{171}Yb, following the proposition made by K…
Bose-Einstein condensate in gases of rare atomic species
Seiji Sugawa, Rekishu Yamazaki, Shintaro Taie +1
We report on the successful extension of production of Bose-Einstein Condensate (BEC) to rare species. Despite its low natural abundance of 0.13%, Yb is directly evaporativ…
Nanometer-scale spatial modulation of an inter-atomic interaction in a Bose-Einstein condensate
Rekishu Yamazaki, Shintaro Taie, Seiji Sugawa +1
We demonstrate nanometer-scale spatial control of inter-atomic interactions in a Bose-Einstein condensate of ytterbium(Yb). A pulsed optical standing wave, tuned near an optical Fe…
