A. D. Chen, M. C. Gandikota, A. Cacciuto

AI总结:

本研究通过数值模拟探究纵向平行切割对弹性膜形状的影响,发现切割会导致膜塌缩为可通过切割参数调控的复杂形貌,且无自回避的刚性膜的回转半径与切割数的关系经重标度后符合普适主曲线。

摘要:

柔性自回避弹性表面(膜)的一个显著特性是,即使不存在弯曲刚度或存在主动涨落,它们在所有温度下都能保持平坦。本文中,我们报告了针对这类表面的数值研究结果,研究中我们通过系统性地切割内部键来改变其拓扑结构。虽然已知随机移除膜的键不会破坏膜整体的延展形状,但我们发现,对弹性表面进行纵向平行切割会导致其系统性地塌缩为多种复杂形貌,这些形貌可以通过改变切割的数量和长度来调控。对于具有弯曲刚度但不存在自回避的更简单膜的情况,我们发现,当对变量进行适当的重标度后,表面的回转半径随切割数量变化的关系可以用一条普适主曲线来描述。

英文摘要:

A remarkable property of flexible self-avoiding elastic surfaces (membranes) is that they remain flat at all temperatures, even in the absence of a bending rigidity or in the presence of active fluctuations. Here, we report numerical results of these surfaces wherein we alter their topology by systematically cleaving internal bonds. While it is known that a random removal of membrane bonds does not disrupt the overall extended shape of the membrane, we find that cleaving an elastic surface with longitudinal parallel cuts leads to its systematic collapse into a number of complex morphologies that can be controlled by altering the number and length of the inserted cuts. For the simpler case of membranes with bending rigidity but in the absence of self-avoidance, we find that the radius of gyration of the surface as a function of number of cuts is represented by a universal master curve when the variables are appropriately rescaled.
