通过对多核生长模型的详细研究,发展了一维Kardar-Parisi-Zhang生长的标度理论。特别是,我们确定了三个普遍分布的形状波动和它们对宏观形状的依赖。这些分布函数是使用高斯随机矩阵在余弦势中的配分函数计算的。
We develop a scaling theory for Kardar-Parisi-Zhang growth in one dimension by a detailed study of the polynuclear growth model. In particular, we identify three universal distributions for shape fluctuations and their dependence on thr macroscopic shape. These distribution functions are computed using the partition function of Gaussian random matrices in a cosine potential.
