“…Implementing the control of chaos-order transition is of fundamental importance in nonlinear science [37,38] and may find span-new applications in chaotic encryption and chaosbased secure communication [27][28][29]. In our scheme we find that the magnon chaos-order transition is phase-mediated, namely, one can easily tailor the optomagnonical system enters or withdraws chaotic regime just by harnessing the relative phase of the microwave driving field.…”

Magnon as a quantized spin wave has attracted extensive attentions in various fields of physics, such as magnon spintronics, microwave photonics, and cavity quantum electrodynamics. Here, we explore theoretically magnon chaos-order transition in cavity optomagnonics, which is still remains largely unexplored in this emerging field. We find that the evolution of the magnon experiences the transition from order to period-doubling bifurcation and finally enter chaos by adjusting the microwave driving power. Different from the normal chaos, the magnon chaos-order transition proposed here is phase-mediated. Beyond their fundamental scientific significance, our results will contribute to the comprehending of nonlinear phenomena and chaos in optomagnonical system, and may find applications in chaos-based secure communication.

“…It is still an open question whether microscopic optomechanical systems with chaotic motion can be synchronized. Optomechanical systems with strong nonlinear light-matter interactions can support quite different types of motion, i.e., periodic [12], quasiperiodic [21], and chaotic [19][20][21][22][23][24]. Thus, the study of chaotic synchronization of optomechanical systems may provide an answer to this question.…”

The synchronization of the motion of microresonators has attracted considerable attention. In previous studies, the microresonators for synchronization were studied mostly in the linear regime. While the important problem of synchronizing nonlinear microresonators was rarely explored. Here we present theoretical methods to synchronize the motions of chaotic optical cavity modes in an optomechanical system, where one of the optical modes is strongly driven into chaotic motion and transfers chaos to other weakly driven optical modes via a common mechanical resonator. This mechanical mode works as a common force acting on each optical mode, which, thus, enables the synchronization of states. We find that complete synchronization can be achieved in two identical chaotic cavity modes. For two arbitrary nonidentical chaotic cavity modes, phase synchronization can also be achieved in the strong-coupling small-detuning regime.

“…The classical trajectories or rays confine independently in regions of classical phase space and cannot penetrate the barriers. In quantum or wave systems, they are connected by dynamical tunneling . The dynamical tunneling in optical microcavities with mixed phase space structures have been thoroughly studied by many groups.…”

In mixed phase space structures, the stable islands and chaotic sea are separated by dynamical barriers. Considering the small tunneling rate, intuitively, the properties of long‐lived resonances within stable islands are supposed to be less affected by the perturbations in chaotic sea. Here, the modifications on the chaotic sea which can be transported through dynamical barriers and strongly affect long‐lived resonances within stable islands are experimentally demonstrated. In waveguide‐connected quadruple microdisks (WCQMs), the finite orbital angular momentum and the propagation directions of long‐lived resonances within stable islands could be changed and controlled by the waveguides connecting to the chaotic sea. The numerical calculations and the corresponding 4 × 4 non‐Hermitian Hamiltonian theoretical model match the experimental results well and demonstrate the essential roles of asymmetrical scattering in the chaotic sea and chaotic‐to‐regular tunneling. This research will be interesting for fundamental studies on quantum chaos and practical applications in optical sensing.
