三维-三维对应的大$N$扭曲配分函数与全息

Large $N$ twisted partition functions in 3d-3d correspondence and Holography

Dongmin Gang, Nakwoo Kim

摘要:

本文研究了双曲三维流形$M$上缠绕$N$ M5-膜的低能极限所产生的三维$\mathcal{N}=2$超共形场论在$\mathcal{M}_{g,p}$上的扭曲配分函数的大$N$极限,即亏格为$g$的黎曼曲面上的$p$度的$S^1$丛.通过3D-3D对应研究了$M$上两个正则不可约$SL(N, \mathbb{C})$平坦联络对应的两个Bethe真空的贡献.利用平坦连接周围微扰Chern-Simons不变量的数学结果,我们找到了两个Bethe真空贡献的大$N$扭曲配分函数的普适表达式,该函数表示为$M$的双曲体积。这两个大的$N$配分函数分别与全息对偶$AdS_4$引力中两个Bolt型解的壳上作用量完全匹配。

英文摘要:

We study the large $N$ limit of twisted partition functions on $\mathcal{M}_{g,p}$, the $S^1$ bundle of degree $p$ over a Riemann surface of genus $g$, for 3D $\mathcal{N}=2$ superconformal field theories arising as low-energy limit of wrapped $N$ M5-branes on hyperbolic 3-manifold $M$. We study contributions from two Bethe vacua which correspond to two canonical irreducible $SL(N, \mathbb{C})$ flat connections on $M$ via 3D-3D correspondence. Using mathematical results on perturbtaive Chern-Simons invariants around the flat connections, we find universal expressions for the large $N$ twisted partition functions contributed from the two Bethe vacua in term of the hyperbolic volume of $M$. The two large $N$ partition functions perfectly match the on-shell actions for two Bolt-type solutions in the holographic dual $AdS_4$ gravity respectively.
