伊辛模型的引力对偶

The Gravity Dual of the Ising Model

Alejandra Castro, Matthias R. Gaberdiel, Thomas Hartman, Alexander Maloney, Roberto Volpato

摘要:

本文在量子体系中计算了三维引力理论的配分函数,其中AdS半径为普朗克尺度,中心荷为一阶。在某些假设下,可以计算AdS真空区的贡献,并等于极小模型CFT的真空特性。环面配分函数由有限且可计算的几何上的和给出。对于牛顿常数G和AdS半径L的一般值,结果没有希尔伯特空间解释,但在某些情况下,它与已知CFT的配分函数一致。例如,G=3L的纯爱因斯坦引力的配分函数等于伊辛模型的配分函数,这就证明了这些理论是对偶的。我们还提供了一些较弱的证据,证明三态和三临界Potts模型分别与基于SL(3)和E_6的纯高自旋引力理论是对偶的。

英文摘要:

We evaluate the partition function of three dimensional theories of gravity in the quantum regime, where the AdS radius is Planck scale and the central charge is of order one. The contribution from the AdS vacuum sector can - with certain assumptions - be computed and equals the vacuum character of a minimal model CFT. The torus partition function is given by a sum over geometries which is finite and computable. For generic values of Newton's constant G and the AdS radius L the result has no Hilbert space interpretation, but in certain cases it agrees with the partition function of a known CFT. For example, the partition function of pure Einstein gravity with G=3L equals that of the Ising model, providing evidence that these theories are dual. We also present somewhat weaker evidence that the 3-state and tricritical Potts models are dual to pure higher spin theories of gravity based on SL(3) and E_6, respectively.
