我们探索了重整化纠缠熵在各种全息模型中的行为：非共形膜；QCD的Witten模型；UV共形RG流由显式和自发对称破缺和Schrödinger几何形状驱动。聚焦于平板纠缠区域，我们发现重整化纠缠熵捕获了先前定义的熵c函数的特征，但也捕获了c函数看不到的深红外行为。特别是，在具有对称破断的理论中，大纠缠区域的重整化纠缠熵饱和到由对称破断参数控制的值。
We explore the behaviour of renormalized entanglement entropy in a variety of holographic models: non-conformal branes; the Witten model for QCD; UV conformal RG flows driven by explicit and spontaneous symmetry breaking and Schrödinger geometries. Focussing on slab entangling regions, we find that the renormalized entanglement entropy captures features of the previously defined entropic c-function but also captures deep IR behaviour that is not seen by the c-function. In particular, in theories with symmetry breaking, the renormalized entanglement entropy saturates for large entangling regions to values that are controlled by the symmetry breaking parameters.
