Einstein-Maxwell-Dilaton理论的全息重整化

Holographic Renormalization of Einstein-Maxwell-Dilaton Theories

Bom Soo Kim

摘要:

我们推广了Einstein-Maxwell-Dilaton理论中包含规范场和标量场的混合边界条件的边值问题。特别地,对偶标量算子的期望值可以是当前算子的期望值的函数。这些性质在固定电荷系综中是普遍的,因为守恒电荷通过非费米耦合被两个场共享,这也是非费米液体性质的原因。我们研究了壳上作用量和应力能张量,以说明边值问题的实际意义。在标量场的存在下,由于无质量标量或质量饱和Breitenlohner-Freedman边界的标量中的有限边界项,物理量不是完全固定的。

英文摘要:

We generalize the boundary value problem with a mixed boundary condition that involves the gauge and scalar fields in the context of Einstein-Maxwell-Dilaton theories. In particular, the expectation value of the dual scalar operator can be a function of the expectation value of the current operator. The properties are prevalent in a fixed charge ensemble because the conserved charge is shared by both fields through the dilaton coupling, which is also responsible for non-Fermi liquid properties. We study the on-shell action and the stress energy tensor to note practical importances of the boundary value problem. In the presence of the scalar fields, physical quantities are not fully fixed due to the finite boundary terms that manifest in the massless scalar or the scalar with mass saturating the Breitenlohner-Freedman bound.
