Multi-state interferometric measurement of nonlinear AC Stark shift
Junnosuke Takai, Kosuke Shibata, Naota Sekiguchi +1
We demonstrate measurement of quadratic AC Stark shifts between Zeeman sublevels in an Rb Bose--Einstein condensate using a multi-state atomic interferometer. The interferom…
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…
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…
