全息纠缠熵对RG流的约束

Constraints on RG Flows from Holographic Entanglement Entropy

Sera Cremonini, Xi Dong

摘要:

我们研究RG流的候选人c-功能,提取的全息纠缠熵的带状区域,与打破洛伦兹不变性的理论。我们澄清的几何形状,导致故障的单调RG流的通用洛伦兹违反场论所预期的条件。然而,我们确定了一组简单的标准上的UV行为的几何保证单调的c-函数。因此,我们的分析可以作为一个指导原则的单调RG轨迹的建设,也可以证明是有用的排除可能的IR行为的理论。

英文摘要:

We examine the RG flow of a candidate c-function, extracted from the holographic entanglement entropy of a strip-shaped region, for theories with broken Lorentz invariance. We clarify the conditions on the geometry that lead to a break-down of monotonic RG flows as is expected for generic Lorentz-violating field theories. Nevertheless we identify a set of simple criteria on the UV behavior of the geometry which guarantee a monotonic c-function. Our analysis can thus be used as a guiding principle for the construction of monotonic RG trajectories, and can also prove useful for excluding possible IR behaviors of the theory.
