Noise-induced transitions in optomechanical synchronization

Abstract

We study how quantum and thermal noise affects synchronization of two\noptomechanical limit-cycle oscillators. Classically, in the absence of noise,\noptomechanical systems tend to synchronize either in-phase or anti-phase.\nTaking into account the fundamental quantum noise, we find a regime where\nfluctuations drive transitions between these classical synchronization states.\nWe investigate how this "mixed" synchronization regime emerges from the\nnoiseless system by studying the classical-to-quantum crossover and we show how\nthe time scales of the transitions vary with the effective noise strength. In\naddition, we compare the effects of thermal noise to the effects of quantum\nnoise.\n
