摘要
遵循Komargodski和Schwimmer在arXiv:1107.3987和arXiv:1112.4538中发展的思想，我们论证了锥上的红外膨胀子有效作用计算了在紫外和红外不动点之间插值的偶维非共形场论的纠缠熵。我们关注流向平凡红外不动点的理论。我们得到了这些场论在任意偶维中对数发散项系数的精确非微扰结果。结果与文献中可用的弱耦合结果以及通过全息术获得的强耦合结果精确匹配。我们还为在尺度不变但非共形不变的紫外不动点与平凡红外不动点之间插值的场论写出了普适项。

Latex, 25 Pages, When the theory reaches a non-trivial fixed point in the IR there is some problem due to IR divergence which need to be taken into account carefully. This will be the part of a forthcoming publication. The results of the previous version remain unchanged when the flow is towards a trivial IR fixed point
