摘要：
通过二维空间中的蒙特卡洛计算机模拟，探索了具有L形的手性粒子的自组装行为。在足够高的填充密度下，由于L形粒子的互锁，出现了类似地毯的纹理，类似于扭曲的近晶液晶层状图案。从粒子的两个轴中任一轴的位置，可以提取出两种不同类型的层，它们形成不同但互补的纠缠网络。随后，从拓扑的角度对这些粗粒化网络结构进行了分析。我们利用与单轴近晶相的类比，提出了一个全局电荷守恒定律，并表明单个网络的拓扑可以通过限制条件和粒子几何形状来控制。我们的拓扑分析为其他相互交织的双网络的应用提供了一个通用的分类框架。
英文摘要：
Self-assembly of chiral particles with an L-shape is explored by Monte-Carlo computer simulations in two spatial dimensions. For sufficiently high packing densities in confinement, a carpet-like texture emerges due to the interlocking of L-shaped particles, resembling a distorted smectic liquid crystalline layer pattern. From the positions of either of the two axes of the particles, two different types of layers can be extracted, which form distinct but complementary entangled networks. These coarse-grained network structures are then analyzed from a topological point of view. We propose a global charge conservation law by using an analogy to uniaxial smectics and show that the individual network topology can be steered by both confinement and particle geometry. Our topological analysis provides a general classification framework for applications to other intertwined dual networks.
