SYK模型和Page曲线中的含时纠缠熵

Time dependent Entanglement Entropy in SYK models and Page Curve

Daniel L. Nedel

摘要:

在这项工作中,两个SYK模型之间提出了新的相互作用项,它允许定义一个相互作用的图片,这样就有可能准确地计算真空态的时间演化。结果表明,真空演化为与时间相关的$SU(2)$压缩态。计算了与时间相关的纠缠熵,其形式与黑洞形成和蒸发的Page曲线相同。

英文摘要:

In this work new interaction terms between two SYK models are proposed, which allow to define an interaction picture such that it is possible to calculate exactly the vacuum state's time evolution. It is shown that the vacuum evolves as a time dependent $SU(2)$ squezed state. The time dependent entanglement entropy is calculated and it has the same form of the Page curve of Black Hole formation and evaporation.
