摘要翻译:
基于对称性、守恒定律和多尺度变元,并利用粗化动力学的相关性,我们提出了一种通用的形式,它允许我们导出描述一维和各向同性二维界面系统的发展方程。我们的方法在表面形态不稳定的情况下变得特别重要,并允许我们在这些系统的连续统描述中对最相关的非线性项进行分类。这种形式适用于从腐蚀的纳米结构到宏观图形形成的系统。特别地,我们证明了该理论在离子等离子体侵蚀实验中的有效性。

英文摘要:
We present a general formalism which allows us to derive the evolution equations describing one-dimensional (1D) and isotropic 2D interfacelike systems, that is based on symmetries, conservation laws, multiple scale arguments, and exploits the relevance of coarsening dynamics. Our approach becomes especially significant in the presence of surface morphological instabilities and allows us to classify the most relevant nonlinear terms in the continuum description of these systems. The formalism applies to systems ranging from eroded nanostructures to macroscopic pattern formation. In particular, we show the validity of the theory for novel experiments on ion plasma erosion.
