论文摘要
通常认为，通过其边界弱耦合到热环境的大型系统，即使环境温度突然变化，也会对新平衡进行准确的放松。在这里，我们展示了即使在无限弱耦合的情况下，这种直观的图片如何破坏离散的能量系统。我们在Ising链中提供了一个例子，显示了自由度之间的相互作用如何产生造型造成远距离平衡的波纹能量景观，并允许异常的放松效应以生存无限弱的耦合。
It is commonly assumed that a large system, weakly coupled to a thermal environment through its boundaries, relaxes quasistatically towards the new equilibrium even when the temperature of the environment changes abruptly. Here we show how this intuitive picture can break down for discrete energy systems, even in the case of infinitely weak coupling. We provide an example in the Ising chain, showing how the interaction among degrees of freedom can create corrugated energy landscapes that are responsible for far-from-equilibrium and allow anomalous relaxation effects to survive infinitely weak couplings.
