论文摘要
使用langevin Dynamics模拟探索了运动相互作用磁盘集合的运动性相位分离现象（MIP）的相图，并特别强调了磁盘壁柔软度和磁盘之间的相互作用范围。由于磁盘的柔软度和惯性，我们在MIP相图中提出了重要的变化。具体而言，我们表明，仅在惯性极限内使用更硬磁盘，MIPS才有可能分开，而MIPS可以分开。与大多数考虑使用硬核磁盘的MIP的早期研究不同，我们的发现可能直接适用于一系列生物系统的软活动物质。
Phase diagram of the phenomenon of motility induced phase separation (MIPS) for a collection of self-propelled interacting disks is explored using Langevin dynamics simulation with particular emphasis on disk wall softness and the range of interaction amongst disks. We bring out important changes in the MIPS phase diagram both due to softness and inertia of the disks. Specifically, we show that overdamped softer disks phase separate while MIPS becomes possible only for harder disks in the inertial limit. Unlike most of the earlier studies on MIPS which consider hard-core disks, our findings may be directly applicable to soft active matter for a range of biological systems.
