论文摘要
使用数值精确的方法，我们检查了Fermi-Hubbard模型关于任意群集拓扑的模型。我们专注于一个问题，当最初在系统和浴室之间高度纠缠的状态下制备相互作用时，最终在互动淬灭之后平衡甚至热量化的问题。我们发现，在可整合簇中的运动常数阻止了对热状态的平衡。我们讨论在平衡和热化过程中波动的大小以及整合性的影响。研究了实际空间拓扑，尤其是无限范围图对平衡和热化的影响。
Using numerically exact methods we examine the Fermi-Hubbard model on arbitrary cluster topology. We focus on the question which systems eventually equilibrate or even thermalize after an interaction quench when initially prepared in a state highly entangled between system and bath. We find that constants of motion in integrable clusters prevent equilibration to the thermal state. We discuss the size of fluctuations during equilibration and thermalization and the influence of integrability. The influence of real space topology and in particular of infinite-range graphs on equilibration and thermalization is studied.
