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…
Sensitive BEC magnetometry with optimized probing
Naota Sekiguchi, Aki Torii, Hiroyuki Toda +4
An improved spatial magnetometer using a spinor Bose-Einstein condensate of Rb atoms is realized utilizing newly developed two-polarization phase contrast imaging. The optic…
Compensation of gravity on cold atoms by a linear optical potential
Kosuke Shibata, Hidehiko Ikeda, Ryota Suzuki +1
We demonstrate gravity compensation for an ultracold gas of Rb atoms with a time-averaged optical potential. The position of a far-off-resonance beam is temporally modulated…
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…
Interaction modulation in a long-lived Bose-Einstein condensate by rf coupling
Kosuke Shibata, Aki Torii, Hitoshi Shibayama +3
We demonstrate modulation of the effective interaction between the magnetic sublevels of the hyperfine spin in a Rb Bose-Einstein condensate by Rabi coupling with radi…
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…
