论文摘要
这些是在Les Houches暑期学校提供的简短课程的讲义，该讲义是``原子和冷凝物理学中的整合性''，2018年夏季。在这里，我在这里进行了教学上的最新进展，研究了在孤立的集成量子系统的非平衡动态过程中纠缠范围扩散的进步。我首先介绍了这样的想法，即固定的热力学熵是在非平衡动力学过程中积累的纠缠，然后将这种想法与准粒子图片相结合，以供纠缠扩散，以提供对任意集成模型中纠缠熵的时间演化的定量预测，无论交互强度如何。
These are lecture notes for a short course given at the Les Houches Summer School on ``Integrability in Atomic and Condensed Matter Physics'', in summer 2018. Here, I pedagogically discuss recent advances in the study of the entanglement spreading during the non-equilibrium dynamics of isolated integrable quantum systems. I first introduce the idea that the stationary thermodynamic entropy is the entanglement accumulated during the non-equilibrium dynamics and then join such an idea with the quasiparticle picture for the entanglement spreading to provide quantitive predictions for the time evolution of the entanglement entropy in arbitrary integrable models, regardless of the interaction strength.
