格点规范理论--五维空间中的引力二元性和库仑常数

Lattice Gauge Theory - Gravity duality and Coulomb's constant in five dimensions

Nikos Irges

摘要:

本文的目的是在非共形、非超对称的背景下对规范理论-引力对偶性进行定量检验。为了做到这一点,我们定义了k5,从威尔逊圈中提取的对象,它在五维SU(N)规范理论中扮演库仑常数的角色,我们认为它的优点之一是它对N的敏感性最小。这使我们可以一方面从大量N个D4-膜的引力反作用计算k5,另一方面从N=2的格点平均场展开计算k5。我们发现这两种方法之间有2%的数值一致性。

英文摘要:

The purpose of this paper is to perform a quantitative check of gauge theory - gravity duality in a nonconformal, nonsupersymmetric context. In order to do so we define k5, an object extracted from the Wilson Loop, that plays the role of Coulomb's constant for SU(N) gauge theories in five dimensions and we argue that one of its virtues is that it could be minimally sensitive to N. This allows us to compute k5 on one hand from the gravitational backreation of a large number N of D4-branes, and on the other from a lattice mean-field expansion for N=2. We find a 2% numerical agreement between the two approaches.
