向错在确定可变形流体界面形态中的作用
Role of disclinations in determining the morphology of deformable fluid interfaces
摘要：
我们研究的平衡形状的囊泡，与平面内的有序，使用蒙特卡洛计划，并表明，高度弯曲的形状，如管和光盘，具有惊人的相似性，由某些曲率敏感外周膜蛋白产生的结构，可以自发产生的各向异性方向曲率与向异性向错发挥重要作用。我们发现，双阶和局部曲率之间的耦合可能会导致类似的缺陷向对方移动，不一样的缺陷远离，从而导致管的形成。热致缺陷对的产生导致分支管状结构。它还表明，螺旋排列的膜管，与周围的螺旋场，是一个占主导地位的软模式的系统。
英文摘要：
We study the equilibrium shapes of vesicles, with an in-plane nematic order, using a Monte-Carlo scheme and show that highly curved shapes, like tubes and discs, with a striking similarity to the structures engendered by certain curvature sensing peripheral membrane proteins, can be spontaneously generated by anisotropic directional curvature with nematic disclinations playing and important role. We show that the coupling between nematic order and local curvature could lead to like defects moving towards each other and unlike defects moving away, in turn leading to tube formation. Thermally induced defect pair production lead to branched tubular structures. It is also shown that helical arrangement of the membrane tubes, with nematic field spiraling around it, is a dominant soft mode of the system.
