Noise-Induced Transitions in Optomechanical Synchronization

TL;DR

This paper explores how quantum and thermal noise influence the synchronization behavior of optomechanical oscillators, revealing noise-driven transitions between classical synchronization states and analyzing the crossover from classical to quantum regimes.

Contribution

It introduces a detailed analysis of noise-induced transitions in optomechanical synchronization, highlighting the effects of quantum versus thermal noise and the classical-to-quantum crossover.

Findings

Quantum noise induces transitions between in-phase and anti-phase states.

Transition time scales depend on noise strength.

Quantum noise can cause mixed synchronization regimes.

Abstract

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