我们研究流体膜中定向相排序的动力学。通过数值模拟，我们发现拓扑纹理的粗化异常缓慢，这受到膜曲率的次扩散传播的限制。方向相关长度xi的增长遵循幂律xi比例，后期的变体t(w)，其中w<1/4。我们还将讨论由曲率弹性介导的长程相互作用的缺陷轮廓和相关模式。
We study the dynamics of orientational phase ordering in fluid membranes. Through numerical simulation we find an unusually slow coarsening of topological texture, which is limited by subdiffusive propagation of membrane curvature. The growth of the orientational correlation length xi obeys a power law xi proportional, variant t(w) with w<1/4 in the late stage. We will also discuss defect profiles and correlation patterns in terms of long-range interaction mediated by curvature elasticity.
