Universal Distributions for Growth Processes in 1+1 Dimensions and Random Matrices
Michael Praehofer, Herbert Spohn
Abstract
We develop a scaling theory for KPZ growth in one dimension by a detailed study of the polynuclear growth (PNG) model. In particular, we identify three universal distributions for shape fluctuations and their dependence on the macroscopic shape. These distribution functions are computed using the partition function of Gaussian random matrices in a cosine potential.
