Abstract: | Tunneling dynamics of multi-atomic molecules between any two multi-atomic molecular Bose-Einstein condensates with Feshbach resonance
is investigated. It is indicated that the tunneling in the two Bose-Einstein
condensates depends not only on the inter-molecular nonlinear interactions
and the initial number of molecule in these condensates, but also on the
tunneling coupling between them. It is discovered that besides oscillating
tunneling current between the multi-atomic molecular condensates, the
nonlinear multi-atomic molecular tunneling dynamics sustains a self-locked population imbalance: a macroscopic quantum self-trapping effect. The influence of de-coherence caused by non-condensate molecule on the
tunneling dynamics is studied. It is shown that de-coherence suppresses the
multi-atomic molecular tunneling. |
