Dispersive measurement of spin shot noise in a Bose--Einstein condensate
Kosuke Shibata, Naota Sekiguchi, Junnosuke Takai +1
We report dispersive spin shot noise measurement of a Bose--Einstein condensate (BEC). While dispersive probing has been used for quantum spin noise measurement of thermal and cold…
Quantum lock-in detection of a vector light shift
Kosuke Shibata, Naota Sekiguchi, Takuya Hirano
We demonstrate detection of a vector light shift (VLS) using the quantum lock-in method. The method offers precise and accurate VLS measurement without being affected by real magne…
Faraday patterns generated by Rabi oscillation in a binary Bose-Einstein condensate
Terun Chen, Kosuke Shibata, Yujiro Eto +2
The interaction between atoms in a two-component Bose-Einstein condensate (BEC) is effectively modulated by the Rabi oscillation. This periodic modulation of the effective interact…
Dissipation-assisted coherence formation in a spinor quantum gas
Yujiro Eto, Hitoshi Shibayama, Kosuke Shibata +4
Dissipation affects all real-world physical systems and often induces energy or particle loss, limiting the efficiency of processes. Dissipation can also lead to the formation of d…
Loading of atoms into an optical trap with high initial phase-space density
Kosuke Shibata, Shota Yonekawa, Satoshi Tojo
We report a method for loading cold atoms into an optical trap with high initial phase-space density (PSD). When the trap beam is overlapped with atoms in optical molasses of optim…
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…
