    Self-Similarity and Power-Law Spectra of Polymer Melts and Solutions by Jehyeok Choi, Kwang Soo Cho, Mi Kyung Kwon

    Published 2022-09-01
    “…The concept of self-similarity has offered a simple solution to many problems in polymer physics. Since the solutions derived from self-similarity are power-law functions, it is essential to check whether the relaxation spectrum of polymeric fluids can be derived by self-similarity. …”

    Structural changes in chromosomes driven by multiple condensin motors during mitosis by Atreya Dey, Guang Shi, Ryota Takaki, D. Thirumalai

    Published 2023-04-01
    “…The loops, which overlap each other, are stapled to a central dynamically changing helical scaffold formed by the motors during the LE process. A polymer physics-based data-driven method that uses the Hi-C contact map as the only input shows that the helix is characterized as random helix perversions (RHPs) in which the handedness changes randomly along the scaffold. …”

    Force-Extension Curve of a Polymer Chain Entangled with a Static Ring-Shaped Obstacle by Qihao Zhang, Jianfeng Li

    Published 2022-10-01
    “…The way to theoretically approach dynamic and static topological constraints of polymer entanglements still presents a great challenge in polymer physics. So far, only the problem of static entanglement with multiple simple objects has been solved in theory by a superspace approach in our previous work. …”

    Ring Polymers: Threadings, Knot Electrophoresis and Topological Glasses by Davide Michieletto, Davide Marenduzzo, Enzo Orlandini, Matthew S. Turner

    Published 2017-08-01
    “…Elucidating the physics of a concentrated suspension of ring polymers, or of an ensemble of ring polymers in a complex environment, is an important outstanding question in polymer physics. Many of the characteristic features of these systems arise due to topological interactions between polymers, or between the polymers and the environment, and it is often challenging to describe this quantitatively. …”

    Nonequilibrium structural and dynamic behaviors of polar active polymer controlled by head activity by Jia-Xiang Li, Song Wu, Li-Li Hao, Qun-Li Lei, Yu-Qiang Ma

    Published 2023-10-01
    “…Thermodynamic behavior of polymer chains out of equilibrium is a fundamental problem in both polymer physics and biological physics. By using molecular dynamics simulation, we discover a nonequilibrium mechanism that controls the conformation and dynamics of polar active polymer; i.e., head activity commands the overall chain activity, resulting in a re-entrant swelling of active chains and a nonmonotonic variation of the Flory exponent ν. …”
