论文摘要
我们研究了使用分子动力学模拟从良好的溶剂溶液到较差的溶液后，我们研究了柔性聚合物链的线圈环链中的非平衡动力学。每个珠子的活性是通过众所周知的Vicsek样对准规则引入的，因此，珠子的速度试图朝着其邻居的平均方向保持一致。我们研究了该聚合物塌陷期间淬灭温度的作用。我们发现，尽管对于较低的活动，但对于不同的温度，动力学在质量上仍然相似，但可以确定较高的活动差异。
We study the nonequilibrium kinetics during the coil-globule transition of a flexible polymer chain with active beads after a quench from good to poor solvent condition using molecular dynamics simulation. Activity for each bead is introduced via the well-known Vicsek-like alignment rule due to which the velocity of a bead tries to align towards the average direction of its neighbors. We investigate the role of quenching temperature with varying activity during collapse of this polymer. We find that although for lower activities the kinetics remains qualitatively similar for different temperatures, for higher activity noticeable differences can be identified.
