无相互作用可穿越虫洞

Traversable wormhole without interaction

Nilakash Sorokhaibam

摘要:

我们发现,强量子纠缠可以支持一个稳定的可穿越的虫洞之间没有任何显式的相互作用或隧道项的两个边界理论的虫洞。具体来说,我们使用两个复杂的SYK模型。纠缠态是在虚时间中利用隧穿项制备的,但是隧穿项从时间演化算符中去除,因此两个复杂的SYK模型没有耦合。低温状态显示复苏动力学,这是一个可穿越的虫洞几何的标志。要将任何有意义的信息从一个系统发送到另一个系统,只需要打开一个非常小的交互项。我们所采用的技术可以应用于其他系统,以研究量子纠缠的各个方面。

英文摘要:

We show that strong quantum entanglement can support a stable traversable wormhole without any explicit interaction or tunnelling term between the two boundary theories of the wormhole. Specifically we work with two complex SYK models. The entangled state is prepared using a tunnelling term in imaginary time but the tunnelling term is removed from the time evolution operator so the two complex SYK models are not coupled. Low temperature states show revival dynamics which is the hallmark of a traversable wormhole geometry. To send any meaningful information from one system to the other, one only needs to turn on a very small interaction term. The technique that we are employing can be applied to other systems to study aspects of quantum entanglement.
