论文摘要
向平衡系统添加过渡会增加活动。天真的人,人们会期望这也可以在平衡系统中保持。这种令人惊讶的效果是由于将迄今禁止的过渡添加到越来越少的状态而引起的。我们证明,使用相对简单的模型,如何将过渡到超出平衡系统中增加可能会减少活动,甚至会导致其消失。我们研究了六个相关的动力学晶格气体模型,有些晶格模型表现为天真的预期,而另一些则表现出这种非直觉行为。我们引入了描述模型的半均值近似近似,该模型与我们的数值模拟质量一致。
Adding transitions to an equilibrium system increases the activity. Naively, one would expect this to hold also in out of equilibrium systems. This surprising effect is caused by adding heretofore forbidden transitions into less and less active states. We demonstrate, using relatively simple models, how adding transitions to an out of equilibrium system may in fact reduce the activity and even cause it to vanish. We investigate six related kinetically-constrained lattice gas models, some of which behave as naively expected while others exhibit this non-intuitive behavior. We introduce a semi-mean-field approximation describing the models, which agrees qualitatively with our numerical simulation.
