我们考虑Bialas，Burda和约翰斯顿最近推出的模型的动力学。在平衡时，该模型表现出流体和凝聚相之间的过渡。对于长时间的演化动力学的凝聚具有一个标度制度，我们研究的分析和数值方法。我们确定了占领数概率的标度形式。能量的二次相关行为表明，老化发生在凝聚相中，而不是在流体相中。
We consider the dynamics of a model introduced recently by Bialas, Burda and Johnston. At equilibrium the model exhibits a transition between a fluid and a condensed phase. For long evolution times the dynamics of condensation possesses a scaling regime that we study by analytical and numerical means. We determine the scaling form of the occupation number probabilities. The behaviour of the two-time correlations of the energy demonstrates that aging takes place in the condensed phase, while it does not in the fluid phase.
