旋转能景中的随机流体动力学同步
Stochastic Hydrodynamic Synchronization in Rotating Energy Landscapes
摘要：
流体动力学同步为独立驱动的介观振子中相干拍频态的自发出现提供了一种普遍的机制。这些现象的完整物理图像对于理解纤毛和鞭毛的生物协同运动具有一定的重要性。此外，它可以潜在地提出新的路线，利用同步技术应用的软物质。我们表明，驱动胶体粒子在旋转的能量景观的结果在一个强烈的趋势同步，有利于所有珠旋转的状态。由此产生的动态可以被描述的激活跳跃的过渡率，强烈影响流体力学导致的概率和寿命的同步状态。使用全息光镊，我们定量验证我们的预测在各种空间配置的转子。
英文摘要：
Hydrodynamic synchronization provides a general mechanism for the spontaneous emergence of coherent beating states in independently driven mesoscopic oscillators. A complete physical picture of those phenomena is of definite importance to the understanding of biological cooperative motions of cilia and flagella. Moreover, it can potentially suggest novel routes to exploit synchronization in technological applications of soft matter. We demonstrate that driving colloidal particles in rotating energy landscapes results in a strong tendency towards synchronization, favouring states where all beads rotate in phase. The resulting dynamics can be described in terms of activated jumps with transition rates that are strongly affected by hydrodynamics leading to an increased probability and lifetime of the synchronous states. Using holographic optical tweezers we quantitatively verify our predictions in a variety of spatial configurations of rotors.
