论文摘要
相位同步是指两个或多个系统之间的相位差锁定的一种集体现象，并且已经在具有相同物理特性的系统之间进行了广泛研究，例如机械振荡器与原子结合体之间的同步之间的同步。在这里，我们研究了机械振荡器和原子集合，具有不同物理特性的系统之间的同步行为，并观察到一种新型的同步现象，即相位总和而不是相位差，是锁定的。我们将这种独特的同步称为相抗同步，并表明可以在经典和量子水平上同时实现相反同步，这意味着可以在实验中测试这种新型的集体行为。同样，发现相抗同步和量子相关性之间的一些有趣的连接。
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.
