整合几何学:全息威尔逊RG和膜范例

Integrating out geometry: Holographic Wilsonian RG and the membrane paradigm

Thomas Faulkner, Hong Liu, Mukund Rangamani

摘要:

我们制定了一个全息威尔逊重整化群流的强耦合系统的重力对偶,需要有效地提取低能量的行为,这样的系统的动机。从定义在体时空中的截断面上的场论开始,我们提出,在场论中积分出高能模应该对应于积分出体几何的一部分。我们描述了如何在实践中进行这一过程中的经典引力近似的标量场和矢量场的例子。通过整合出大量的自由度一直到一个黑洞视界,这个公式定义了一个精致的版本的黑洞膜范例。此外,它还提供了一个推导的半全息描述的低能物理。

英文摘要:

We formulate a holographic Wilsonian renormalization group flow for strongly coupled systems with a gravity dual, motivated by the need to extract efficiently low energy behavior of such systems. Starting with field theories defined on a cut-off surface in a bulk spacetime, we propose that integrating out high energy modes in the field theory should correspond to integrating out a part of the bulk geometry. We describe how to carry out this procedure in practice in the classical gravity approximation using examples of scalar and vector fields. By integrating out bulk degrees of freedom all the way to a black hole horizon, this formulation defines a refined version of the black hole membrane paradigm. Furthermore, it also provides a derivation of the semi-holographic description of low energy physics.
