论文摘要
我们适应顶点模型，以了解排斥软颗粒中远程有序结构形成的物理起源。该模型结合了每个粒子的体积和表面积的贡献。使用Monte Carlo模拟进行采样使系统可以自然选择首选结构。我们观察到以身体为中心的立方体有序状态和无序状态之间的过渡。对仿真域的约束可以抑制或允许系统遵循类似于从一个有序状态到另一个有序状态的马氏体转换的路径。最后，我们表明，从无序状态到有序区域的快速淬灭导致亚稳定的局部粒子排列，而不是大规模的单晶。
We adapt Vertex models to understand the physical origin of the formation of long-range ordered structures in repulsive soft particles. The model incorporates contributions from the volume and surface area of each particle. Sampling using Monte Carlo simulations allows the system to naturally select preferred structures. We observe transitions between a body-centered cubic ordered state and a disordered state. Constraints to the simulation domain can suppress or allow the system to follow a path similar to Martensitic transformations from one ordered state to another ordered state. Finally, we show that rapid quenches from a disordered state into the ordered region lead to metastable local particle arrangements instead of a large-scale single crystal.
