TQFT引力与系综全息

TQFT gravity and ensemble holography

Anatoly Dymarsky, Alfred Shapere

AI总结:

本文推导了“TQFT引力”(3维TQFT拓扑求和路径积分)与边界2维CFT系综的全息对偶性,通过极高亏格黎曼曲面的平凡对偶性经亏格约化得到有限亏格结果,普适且保证幺正性,还在阿贝尔Chern-Simons理论中验证了系综权重相等及体拓扑等价类有限求和。

摘要:

我们概述了“TQFT引力”(即对不同拓扑求和的3维TQFT路径积分)与边界2维CFT系综之间全息对偶性的一般推导。关键思想是将边界系综置于极高亏格的黎曼曲面上,此时对偶性变得平凡。有限亏格下的对偶关系通过亏格约化得到。我们的推导具有普适性,不依赖于体或边界配分函数的显式形式,保证了幺正性,并表明体求和应包含所有可能的拓扑。对于具有紧致规范群的阿贝尔Chern-Simons理论,我们证明边界系综的权重相等,而体求和简化为对拓扑等价类的有限求和,由可能带有线缺陷的柄体表示。

英文摘要:

We outline a general derivation of holographic duality between "TQFT gravity" - the path integral of a 3d TQFT summed over different topologies - and an ensemble of boundary 2d CFTs. The key idea is to place the boundary ensemble on a Riemann surface of very high genus, where the duality trivializes. The duality relation at finite genus is then obtained by genus reduction. Our derivation is generic and does not rely on an explicit form of the bulk or boundary partition functions. It guarantees unitarity and suggests that the bulk sum should include all possible topologies. In the case of Abelian Chern-Simons theory with compact gauge group we show that the weights of the boundary ensemble are equal, while the bulk sum reduces to a finite sum over equivalence classes of topologies, represented by handlebodies with possible line defects.
