Symmetry restoring dynamics in a two-species bosonic Josephson junction by using occasional coupling

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 and pi phase 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 the pi-phase mode, the broken symmetry is restored accompanied by the appearance of chaotic MS states.
