迹Anomaly匹配和纠缠熵的精确结果

Trace Anomaly Matching and Exact Results For Entanglement Entropy

Shamik Banerjee

摘要:

根据Komargodski和Schwimmer在arXiv:1107.3987和arXiv:1112.4538中提出的思想,我们论证了红外纠缠子对锥的有效作用量计算了在UV和IR不动点之间插值的偶数维非共形场论的纠缠熵.我们限制我们的注意力流到平凡IR不动点的理论。我们得到了任意偶数维场论中纠缠熵的几何发散项系数的精确非微扰结果。结果与文献中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。我们还写了通用条款的场论之间的尺度不变,但不保形不变的UV不动点和平凡的IR不动点插值。

英文摘要:

Following the ideas developed by Komargodski and Schwimmer in arXiv:1107.3987 and arXiv:1112.4538, we argue that the IR dilaton effective action on the cone computes the entanglement entropy of an even dimensional non-conformal field theory interpolating between a UV and an IR fixed point. We restrict our attention to theories which flow to trivial IR fixed point. We get exact non-perturbative results for the coefficients of the logarithmically divergent term of the entanglement entropy in these field theories in arbitrary even dimensions. The results match precisely with the weak coupling results available in the literature and also with the strong coupling results obtained via holography. We also write the universal terms for field theories which interpolate between a scale invariant but not conformally invariant UV fixed point and a trivial IR fixed point.
