摘要
We present the results of CA simulations of a moderately dense lattice gas using an extended version of the FHP model for colored automata. By tracking a tagged particle, we construct its velocity autocorrelation function and we show that the corresponding power spectrum exhibits a low-frequency contribution characteristic of the long-time power law behavior (almost-equal-to t-1, in 2D).
