AI总结:

本研究将$O(N)$与$Sp(N)$通过$N$负向解析延拓关联的对偶性,从向量模型、规范理论等场景推广至任意阶、无指标置换对称性且含四次相互作用的实随机张量模型,证明该对偶性在微扰论全阶下对配分函数等物理量逐图成立。

摘要:

群$O(N)$和$Sp(N)$通过将$N$解析延拓到负值相关联,即$O(-N)\simeq Sp(N)$。这种对偶性已在向量模型、$SO(N)$与$Sp(N)$规范理论以及部分随机矩阵系综中得到研究。我们将该对偶性推广至任意阶$D$、指标置换无对称性且含四次相互作用的实随机张量模型。研究表明,对于配分函数、自由能和连通两点函数,$N$到$-N$的对偶性在微扰论的所有阶下逐图成立。

英文摘要:

The groups $O(N)$ and $Sp(N)$ are related by an analytic continuation to negative values of $N$, $O(-N)\simeq Sp(N)$. This duality has been studied for vector models, $SO(N)$ and $Sp(N)$ gauge theories, as well as some random matrix ensembles. We extend this duality to real random tensor models of arbitrary order $D$ with no symmetry under permutation of the indices and with quartic interactions. The $N$ to $-N$ duality is shown to hold graph by graph to all orders in perturbation theory for the partition function, the free energy and the connected two point function.
