摘要翻译:
我们研究了在一维和二维波动表面上滑动的随机粒子系统中的聚类。在稳态下,密度-密度相关函数是分离度和系统大小的标度函数,这个标度函数对于小变元是奇异的--对于有互斥的粒子表现出尖点奇异性,对于无相互作用的粒子表现出散度。稳态的特征是巨大的涨落,在热力学极限内不会减弱。自相关函数是时间和系统大小的奇异标度函数。其标度性质与粒子在表面冻结的淬火无序环境中运动时的标度性质惊人地相似。

英文摘要:
We study clustering in a stochastic system of particles sliding down a fluctuating surface in one and two dimensions. In steady state, the density-density correlation function is a scaling function of separation and system size.This scaling function is singular for small argument -- it exhibits a cusp singularity for particles with mutual exclusion, and a divergence for noninteracting particles. The steady state is characterized by giant fluctuations which do not damp down in the thermodynamic limit. The autocorrelation function is a singular scaling function of time and system size. The scaling properties are surprisingly similar to those for particles moving in a quenched disordered environment that results if the surface is frozen.
