论文摘要

两种完全柔性自避免自我的聚合物之间相互作用的表征是聚合物物理学中经典和最重要的问题之一。在本文中,我们在存在主动波动的情况下测量这些相互作用。我们使用该领域中最受欢迎的两个模型将活动介绍给问题。一个活性有效地嵌入了单体的动力学中,另一个被动聚合物在有效颗粒的显式浴中波动。我们确定了可以将活性聚合物之间相互作用映射到经典被动问题的条件。我们观察到,活跃的浴室可以推动聚合物之间强烈的吸引人相互作用的发展,并且在强制重叠时,它们会组合在一起形成一个双链单元。还报道了构象行为变化的相图。

The characterization of the interactions between two fully flexible self-avoiding polymers is one of the classic and most important problems in polymer physics. In this paper we measure these interactions in the presence of active fluctuations. We introduce activity into the problem using two of the most popular models in this field. One where activity is effectively embedded into the monomers' dynamics, and the other where passive polymers fluctuate in an explicit bath of active particles. We establish the conditions under which the interaction between active polymers can be mapped into the classical passive problem. We observe that the active bath can drive the development of strong attractive interactions between the polymers and that, upon enforcing a significant degree of overlap, they come together to form a single double-stranded unit. A phase diagram tracing this change in conformational behavior is also reported.
