论文摘要
我们介绍了一个鞍点的发现器，该发现器可以为任何分析性继续行动找到复杂的鞍点。我们通过EPRL自旋泡沫模型中的两个示例来展示我们的鞍点查找器：单个顶点情况和三角剖分$Δ_3$。在这两种情况下，都发现了复杂的鞍点，并且估计每个鞍点对分区功能的贡献。我们还讨论了每个鞍点的几何解释。
We introduce a saddle-point finder that can find the complex saddle points for any analytically continued action. We showcase our saddle-point finder by two examples in the EPRL spin foam model: the single vertex case and the case of triangulation $Δ_3$. In both cases, the complex saddle points are found, and each saddle point's contribution to the partition function is estimated. We also discuss the geometrical interpretation of each saddle point.
