Classical Bifurcation at the Transition from Rabi to Josephson Dynamics
Classical Bifurcation at the Transition from Rabi to Josephson Dynamics
We report on the experimental demonstration of the internal bosonic Josephson effect in a rubidium spinor Bose-Einstein condensate. The measurement of the full time dynamics in phase space allows the characterization of the theoretically predicted π-phase modes and quantitatively confirms analytical predictions, revealing a classical bifurcation. Our results suggest that …
