摘要

我的研究表明，在被虫洞几何修饰的 AdS 体空间背景下，对纠缠熵的全息计算提供了预期的纠缠量。这是在弦理论的背景下，通过弦在体演化过程中看到的附加几何结构而产生的。这个过程可以描述为向弦几何的净纠缠流。我利用的事实是，与量子场论不同，弦在小的额外维度周围有额外的缠绕模式态，这些模式态修改了龙-高柳纠缠熵公式的标准应用所给出的面积计算。

Strings and Missing Wormhole Entanglement

I show that holographic calculations of entanglement entropy in the context of AdS bulk space modified by wormhole geometries provide the expected entanglement magnitude. This arises in the context of string theory by means of additional geometric structure that is seen by the string in its bulk evolution. The process can be described as a net entanglement flow towards stringy geometry. I make use of the fact that as opposed to quantum field theory, strings have additional winding mode states around small extra dimensions which modify the area computation given by the standard application of the Ryu-Takayanagi entanglement entropy formula.

期刊介绍： International Journal of Theoretical Physics publishes original research and reviews in theoretical physics and neighboring fields. Dedicated to the unification of the latest physics research, this journal seeks to map the direction of future research by original work in traditional physics like general relativity, quantum theory with relativistic quantum field theory,as used in particle physics, and by fresh inquiry into quantum measurement theory, and other similarly fundamental areas, e.g. quantum geometry and quantum logic, etc.
