论文摘要
研究了边界耦合常数在二维形成式磁场理论中的信息指标。这样的度量与在间隔定义的理论的Casimir能量差有关。我们具体地计算了自由玻色子CFT以及SU（2）K WZW理论的边界共形歧管上的信息指标，从而获得了系统对称性的结果。我们还计算了在实际自由标量理论中由边界质量扰动产生的非统一边界状态空间的信息指标。还讨论了在ADS3/BCFT2背景下边界信息指标的全息双重双重双重双重双重双重双重双重二元。我们认为它对应于连接渐近BCFT的两个边界的世界末日的最小横截面区域。
The information metric on the space of boundary coupling constants in two-dimensional conformal field theories is studied. Such a metric is related to the Casimir energy difference of the theory defined on an interval. We concretely compute the information metric on the boundary conformal manifold of free boson CFT as well as SU(2)k WZW theory, obtaining the result expected from the symmetry of the systems. We also compute the information metric on the space of non-conformal boundary states produced by boundary mass perturbations in the theory of a real free scalar. The holographic dual of the boundary information metric in the context of AdS3/BCFT2 is also discussed. We argue that it corresponds to the area of the minimal cross section of the end-of-the-world brane connecting two boundaries of the asymptotic BCFTs.
