随机量子化与全息威尔逊重整化群

Stochastic quantization and holographic Wilsonian renormalization group

Jae-Hyuk Oh, Dileep P. Jatkar

摘要:

研究了随机量子化与全息威尔逊重整化群流的关系。考虑某些$AdS$体引力理论的Dirichlet边界条件下的边界壳作用量的随机量子化,我们发现边界有效作用量中的双迹形变径向流完全被随机时间演化捕获,其中$AdS$径向坐标为$r$,随机时间为$t$.更精确地说,我们研究了Langevin动力学,发现了双迹耦合的径向流与随机量子化中的两点关联函数之间的精确关系。我们还证明了边界有效作用量中双迹形变的径向演化与Fokker-Planck作用量的随机时间演化是一致的。我们用几个例子证明了这种关系:$AdS_2$中的(最小耦合)无质量标量场和$AdS_4$中的U(1)矢量场。

英文摘要:

We study relation between stochastic quantization and holographic Wilsonian renormalization group flow. Considering stochastic quantization of the boundary on-shell actions with the Dirichlet boundary condition for certain $AdS$ bulk gravity theories, we find that the radial flows of double trace deformations in the boundary effective actions are completely captured by stochastic time evolution with identification of the $AdS$ radial coordinate `$r$' with the stochastic time '$t$' as $r=t$. More precisely, we investigate Langevin dynamics and find an exact relation between radial flow of the double trace couplings and 2-point correlation functions in stochastic quantization. We also show that the radial evolution of double trace deformations in the boundary effective action and the stochastic time evolution of the Fokker-Planck action are the same. We demonstrate this relation with a couple of examples: (minimally coupled)massless scalar fields in $AdS_2$ and U(1) vector fields in $AdS_4$.
