论文摘要
纠缠楔形截面（EWCSS）被假定为对多方系统纠缠的某些度量的双重重力探针。我们测试了EWCSS的各种建议的不平等。事实证明，与期望相反，对于三方系统而言，EWC并不明显或一夫多妻制，但结果取决于重力溶液的几何形状的细节和维度。我们提出了双重纠缠措施的较弱的一夫一妻制关系，这导致了EWC上的新下限。我们的工作基于多种重力背景：纯抗De Sitter空间，抗De Sitter Black Branes，由DP-branes堆叠诱导的，以及在通用维度中的雪茄几何形状。
The entanglement wedge cross sections (EWCSs) are postulated as dual gravity probes to certain measures for the entanglement of multiparty systems. We test various proposed inequalities for EWCSs. As it turns out, contrary to expectations, the EWCS is not clearly monogamous nor polygamous for tripartite systems but the results depend on the details and dimensionality of the geometry of the gravity solutions. We propose weaker monogamy relations for dual entanglement measures, which lead to a new lower bound on EWCS. Our work is based on a plethora of gravity backgrounds: pure anti de Sitter spaces, anti de Sitter black branes, those induced by a stack of Dp-branes, and cigar geometries in generic dimension.
