预热化是指在达到热平衡之前弛豫到准稳态。最近，人们发现，不仅是局域守恒量，而且纠缠在一种特殊类型的预热化中起着关键作用，我们称之为纠缠预热化。在这里，我们表明，在Tomonaga-Luttinger模型的纠缠预热也可以解释的两个独立的子系统没有纠缠的传统的预热。此外，由于能量简并的不同，Tomonaga-Luttinger模型中的预热化与Lieb-Liniger模型中的纠缠预热化有着本质的不同.
Prethermalization refers to the relaxation to a quasistationary state before reaching thermal equilibrium. Recently, it was found that not only local conserved quantities but also entanglement plays a key role in a special type of prethermalization, which we refer to as entanglement prethermalization. Here, we show that in the Tomonaga-Luttinger model entanglement prethermalization can also be explained by the conventional prethermalization of two independent subsystems without entanglement. Moreover, it is argued that prethermalization in the Tomonaga-Luttinger model is essentially different from entanglement prethermalization in the Lieb-Liniger model because of the different types of energy degeneracies.
