Phase Anti-Synchronization dynamics between Mechanical Oscillator and Atomic Ensemble within a Fabry-Perot Cavity

TL;DR

This paper explores a novel phase anti-synchronization phenomenon between a mechanical oscillator and an atomic ensemble within a Fabry-Perot cavity, demonstrating its occurrence at classical and quantum levels and its relation to quantum correlations.

Contribution

It introduces the concept of phase anti-synchronization between dissimilar systems and shows its feasibility at both classical and quantum levels, expanding understanding of synchronization phenomena.

Findings

Phase anti-synchronization involves locking of phase sums, not differences.

It occurs in both classical and quantum regimes.

Connections between phase anti-synchronization and quantum correlations are identified.

Abstract

Phase synchronization refers to a kind of collective phenomenon that the phase difference between two or more systems is locked, and it has widely been investigated between systems with the identical physical properties, such as the synchronization between mechanical oscillators and the synchronization between atomic ensembles. Here, we investigate the synchronization behavior between the mechanical oscillator and the atomic ensemble, the systems with different physical properties, and observe a novel synchronization phenomenon, i.e., the phase sum, instead of phase difference, is locked. We refer to this distinct synchronization as the phase anti-synchronization, and show that the phase anti-synchronization can be achieved in both the classical and quantum level, which means this novel collective behavior can be tested in experiment. Also, some interesting connections between phase anti-synchronization and quantum correlation is found.
