Synchronization plays an important role in many physical processes. We discuss synchronization in a molecular dynamics simulation of a single particle moving through a viscous liquid while being driven across a washboard potential energy landscape. Our results show many dynamical patterns as the landscape and driving force are altered. For certain conditions, the particle's velocity and location are synchronized or phase-locked and form closed orbits in phase space. Quasi-periodic motion is common, for which the dynamical center of motion shifts the phase space orbit. By isolating synchronized motion in simulations and table-top experiments, we can study complex natural behaviors important to many physical processes.

驱动粒子同步的分子动力学模拟

同步在许多物理过程中起着重要作用。我们讨论了单个粒子在穿过洗衣板势能景观时穿过粘性液体的分子动力学模拟中的同步。随着景观和驱动力的改变，我们的结果显示了许多动态模式。在某些条件下，粒子的速度和位置是同步的或锁相的，并在相空间中形成闭合轨道。准周期运动是常见的，为此，动态运动中心移动相空间轨道。通过在模拟和桌面实验中隔离同步运动，我们可以研究对许多物理过程很重要的复杂自然行为。
