标题： Cyclic phase transition of substrate-modulated 2D dusty plasma driven by oscillatory forces

摘要： Langevin动力学模拟用于研究由振荡力驱动的二维周期性基底（2DPS）调制的二维尘埃等离子体（2DDP）中团簇和空洞的形成。 发现随着振荡力频率逐渐降低，基底调制的2DDP会经历有序团簇和空洞相之间的循环转变。 在观察到的有序团簇和空洞相之间，研究的2DDP表现出更均匀的粒子排列。 发现的循环转变归因于在移动粒子参考系中由于2DPS导致的时间平均势景观的对称性，这通过在不同条件下将粒子位置叠加在有效势景观上得到了证实。 显示英文摘要

摘要： Langevin dynamical simulations are performed to investigate the formation of clusters and voids of a two-dimensional-periodic-substrate (2DPS) modulated two-dimensional dusty plasma (2DDP) driven by an oscillatory force. It is discovered that, as the frequency of the oscillatory force decreases gradually, the substrate-modulated 2DDP undergoes the cyclic transition of the ordered cluster and void phases. Between the observed ordered cluster and void phases, the studied 2DDP exhibits a more uniform arrangement of particles. The discovered cyclic transition is attributed to the symmetry of the time-averaged potential landscape due to the 2DPS in the reference frame of the moving particle, as confirmed by superimposing the particle locations on the effective potential landscape under various conditions.
