摘要
In this paper,by employing an occasionally coupling scheme in a two-species bosonic Josephson junction,it is found that for nonlocal measure synchronized states appearing in the two dynamic modes,known as 0-phase mode andπphase mode,their broken-symmetry can be restored.Nevertheless,there are dramatic differences for the results.For 0-phase mode,we can restore the broken symmetry by turning the nonlocal MS state into a conventional quasiperiodic MS state.However,for theπ-phase mode,the broken symmetry is restored accompanied by the appearance of chaotic MS states.
