We calculate the expectation value of the Wilson line in the pure AdS$_3$ Einstein gravity theory and also the entanglement entropy in the boundary theory. Our one-loop calculation of entanglement entropy shows a shift of the central charge 26. Finally, we show that the Wilson line provides the equivalent description to the boundary entanglement entropy. This equivalence leads to a concrete example of the building of "minimum surface=entanglement entropy".

纯 AdS3 爱因斯坦引力理论中威尔逊线和纠缠熵的量子校正

我们计算纯 AdS$_3$ 爱因斯坦引力理论中威尔逊线的期望值以及边界理论中的纠缠熵。我们对纠缠熵的单循环计算显示了中心电荷 26 的偏移。最后,我们表明威尔逊线提供了对边界纠缠熵的等效描述。这种等价导致建立“最小表面=纠缠熵”的具体例子。
