关于纠缠熵的T-对偶重整化

On the T-dual renormalisation of entanglement entropy

Andrei T. Patrascu

摘要:

在纠缠熵的重整化过程中引入T-对偶性,得到了纠缠熵反项之间的新关系。在体边界对偶性的背景下,借助于双场论的广义度规,使T-对偶性显式化。体双场论提供了纠缠熵的高阶量子修正之间的新关系,也为理解纠缠熵重整化反项提供了一种系统的方法。提出了一个类似于纠缠熵的T-对偶反项的Slavnov-Taylor恒等式。

英文摘要:

Imposing T-duality in the renormalisation process of entanglement entropy leads to new relations between entanglement entropy counter-terms. T-duality is made explicit by means of the generalised metric of double field theory in the context of bulk-boundary duality. Double field theory in the bulk naturally provides the new relations between higher order quantum corrections to entanglement entropy as well as a systematic approach to understanding entanglement entropy renormalisation counter-terms. An analogue for Slavnov-Taylor identities for T-dual counter-terms of entanglement entropy is envisaged.
