Synchronization in <i>PT</i>-symmetric optomechanical resonators

Synchronization has great impacts in various fields such as self-clocking, communication, and neural networks. Here, we present a mechanism of synchronization for two mechanical modes coupled optomechanical resonators with parity-time ( PT )-symmetric structure. It is shown that the degree between far-off-resonant can be increased by decreasing coupling strength due to large amplification interaction near exceptional point. Additionally, when consider stochastic noises working point, find more enhance system under particular parameter regime. Our results open up new dimension research id="m3"> -symmetric systems synchronization.
