论文摘要
我们研究由外部电场驱动的尺寸和电荷相对充满电的胶体。大颗粒通过谐波弹簧连接，形成六边形晶格网络，而小颗粒没有键并表现出流体样运动。我们表明，当外部驱动力超过临界值时，该模型表现出群集形成模式。聚类伴随着稳定的波袋，其中大颗粒的振动运动。
We study size- and charge-asymmetric oppositely charged colloids driven by an external electric field. The large particles are connected by harmonic springs, forming a hexagonal-lattice network while the small particles are free of bonds and exhibit fluid-like motion. We show that this model exhibits a cluster formation pattern when the external driving force exceeds a critical value. The clustering is accompanied with stable wavepackets in vibrational motions of the large particles.
