论文摘要
在定向有序的球体上的拓扑点缺陷以及可变形的流体囊泡的拓扑缺陷,部分是由于它们在创建具有方向性键合化的超级原子时的潜在应用而引起的,这是由拓扑点缺陷创造的“秃头点”,从而铺平了在微子尺度上的原子化学方法。我们表明,在二维中拓扑上不稳定的“秃头线”的奇异壁缺陷在球体上的订单diSorder转变附近稳定。我们将它们的稳定性归因于自由能考虑,从而覆盖了拓扑稳定性。
Topological point defects on orientationally ordered spheres, and on deformable fluid vesicles have been partly motivated by their potential applications in creating super-atoms with directional bonds through functionalization of the "bald-spots" created by topological point defects, thus paving the way for atomic chemistry at micron scales. We show that singular wall defects, topologically unstable "bald lines" in two dimensions, are stabilized near the order-disorder transition on a sphere. We attribute their stability to free-energetic considerations, which override those of topological stability.
