非欧界面的动态标度

Dynamic Scaling of Non-Euclidean Interfaces

Carlos Escudero

摘要:

弯曲界面的动态缩放呈现出与平面界面显著不同的特征。一维以上的球面是平坦的,因为在这种情况下噪声是不相关的。因此,动力学粗糙化是一种一维现象,其特征在于波动的边际对数振幅。由平面动力学指数$z>1$,其中包括最常见的随机生长方程,其特征在于模型遭受损失的相关性沿界面,和他们的动态减少到径向随机沉积模型在很长的时间限制。在几个应用的后果进行了讨论,我们得出的结论是,有必要重新检查一些实验结果中,标准标度分析应用。

英文摘要:

The dynamic scaling of curved interfaces presents features that are strikingly different from those of the planar ones. Spherical surfaces above one dimension are flat because the noise is irrelevant in such cases. Kinetic roughening is thus a one-dimensional phenomenon characterized by a marginal logarithmic amplitude of the fluctuations. Models characterized by a planar dynamical exponent $z>1$, which include the most common stochastic growth equations, suffer a loss of correlation along the interface, and their dynamics reduce to that of the radial random deposition model in the long time limit. The consequences in several applications are discussed, and we conclude that it is necessary to reexamine some experimental results in which standard scaling analysis was applied.
