Phase-mediated magnon chaos-order transition in cavity optomagnonics
TLDR
In this article, the authors explore theoretically magnon chaos-order transition in cavity optomagnonics, which is still remains largely unexplored in this emerging field, and find that the evolution of the magnon experiences the transition from order to period-doubling bifurcation and finally enters chaos by adjusting the microwave driving power.Abstract:
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.read more
