摘要:

一个Lennard-Jones系统的膨胀动力学,最初被限制在高密度,随后在真空中自由膨胀,面临着一个膨胀的统计系综,在稀释的准理想玻尔兹曼近似。该描述被证明是相当准确的预测平均单体全球可观的,但重要的偏差观察到的事件的配置空间结构。有限扩展的物理系统的可能影响进行了概述。

英文摘要:

The dynamics of the expansion of a Lennard-Jones system, initially confined at high density and subsequently expanding freely in the vacuum, is confronted to an expanding statistical ensemble, derived in the diluted quasi-ideal Boltzmann approximation. The description proves to be fairly accurate at predicting average one-body global observables, but important deviations are observed in the configuration-space structure of the events. Possible implications for finite expanding physical systems are outlined.
