AI 中文摘要
旋转胶体（或旋转器）在障碍物阵列中表现出由惯性、类马格努斯升力和短程吸引力之间的竞争所设定的频率固定的静止轨道和电流。完全解析的格子玻尔兹曼模拟揭示了流体动力耦合并确定了升力机制，而基于对称性的朗之万模型捕捉了由此产生的平衡。在周期性晶格中，标量和矢量势的叠加产生了两种稳健的轨道状态：角状态，旋转器围绕单个柱体轨道运行；内部状态，轨道跨四个相邻障碍物耦合。缓慢的频率调制切换这些状态并产生跨网格的定向、逐步输运。这建立了一种由单个驱动参数控制的最小流体动力机制，用于在结构化环境中对主动转子进行可编程引导。
英文摘要
Rotating colloids, or spinners, in obstacle arrays exhibit frequency-set stationary orbits and currents set by the competition between an inertial, Magnus-like lift and short-range attraction. Fully resolved lattice-Boltzmann simulations reveal the hydrodynamic coupling and identify the lift mechanism, while a symmetry-based Langevin model captures the resulting balance. In periodic lattices, the superposition of scalar and vector potentials produces two robust orbital regimes: corner states, in which spinners orbit individual posts, and inner states, in which orbits couple across four neighboring obstacles. Slow frequency modulation toggles these states and produces directed, stepwise transport across the grid. This establishes a minimal hydrodynamic mechanism, controlled by a single driving parameter, for programmable guidance of active rotors in structured environments.
