球配分函数与截断AdS

Sphere partition functions and cut-off AdS

Pawel Caputa, Shouvik Datta, Vasudev Shyam

摘要:

我们考虑d= 2,3,4,5和6维TT变形大N共形场论的球配分函数,用流动方程计算。这些被证明是非微扰匹配与批量计算的$AdS_{d+1}$有限的径向截止。然后,我们演示了如何流方程可以独立地从一个正则化过程中定义TT运营商通过当地的Callan-Symanzik方程。最后,我们表明,球配分函数,模批量counterterterterm的贡献,可以从惠勒-德维特波函数再现。

英文摘要:

We consider sphere partition functions of TT deformed large N conformal field theories in d=2,3,4,5 and 6 dimensions, computed using the flow equation. These are shown to non-perturbatively match with bulk computations of $AdS_{d+1}$ with a finite radial cut-off. We then demonstrate how the flow equation can be independently derived from a regularization procedure in defining TT operators through a local Callan-Symanzik equation. Finally, we show that the sphere partition functions, modulo bulk-counterterm contributions, can be reproduced from Wheeler-DeWitt wave functions.
