论文摘要
在这篇局部评论中，我们概述了活跃浴，高斯或非高斯的单个聚合物链的结构和动力学。综述首先讨论了单个柔性或半融合线性聚合物链，该链受到两个噪音，即热和有效的声音。主动噪声具有高斯或非高斯分布，但具有记忆，这构成了活动浴粒子的持续运动。这种有限的持久性使链条的重新配置动力学与纯粹的热壳和链条膨胀相比。主动噪声还会导致标记单体的超级延伸或弹道运动。我们详细介绍了所有计算，但主要集中在近年来从我们的小组中获得的分析精确或几乎确切的结果。此外，我们简要提及其他小组的重要作品，并包括我们的一些新结果。审查结束时指出了聚合物链在生物学相关的环境及其未来方向上的活性浴中的含义。
In this topical review, we give an overview of the structure and dynamics of a single polymer chain in active baths, Gaussian or non-Gaussian. The review begins with the discussion of single flexible or semiflexible linear polymer chains subjected to two noises, thermal and active. The active noise has either Gaussian or non-Gaussian distribution but has a memory, accounting for the persistent motion of the active bath particles. This finite persistence makes the reconfiguration dynamics of the chain slow as compared to the purely thermal case and the chain swells. The active noise also results superdiffusive or ballistic motion of the tagged monomer. We present all the calculations in details but mainly focus on the analytically exact or almost exact results on the topic, as obtained from our group in recent years. In addition, we briefly mention important works of other groups and include some of our new results. The review concludes with pointing out the implications of polymer chains in active bath in biologically relevant context and its future directions.
