论文摘要
在这项工作中，提出了两个SYK模型之间的新相互作用项，该术语允许定义相互作用图片，以便可以准确计算真空状态的时间演变。结果表明，真空变成了依赖时间的$ su（2）$ squezed状态。计算时间依赖的纠缠熵，并具有黑洞形成和蒸发的页面曲线的相同形式。
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.
