Title: 活性粒子系统在双势阱势场中的相行为和动力学

Abstract: In this paper, we investigate the phase behaviors and dynamics of self-propelled particles with active reorientation in double-well potential. We observe the self-propelled particles exhibit flocking and clustering in an asymmetric potential trap. By MD simulations, we obtain a phase diagram of flocking with active reorientation and potential asymmetry as parameters. We compare the responses of inactive and active particles to the potential. It shows that active reorientation of particles amplifies the degree of aggregation on one side in the asymmetric potential well. Furthermore, we calculate the mean squared displacement and identify distinct diffusion regimes. These results highlight active particles with active reorientation exhibit greater sensitivity in double-well potentials. Show Chinese abstract

Abstract: 在本文中，我们研究了具有主动重新定向的自推进粒子在双势阱中的相行为和动力学。我们观察到自推进粒子在非对称势阱中表现出 flocking 和聚类。通过 MD 模拟，我们获得了一个以主动重新定向和势不对称为参数的 flocking 相图。我们比较了非活性和活性粒子对势场的响应。结果表明，粒子的主动重新定向会增强非对称势阱中一侧的聚集程度。此外，我们计算了均方位移并识别了不同的扩散区域。这些结果突显出具有主动重新定向的活性粒子在双势阱中表现出更高的敏感性。
