Lifshitz全息:整个Shebang

Lifshitz holography: The whole shebang

Wissam Chemissany, Ioannis Papadimitriou

摘要:

我们提供了一个通用的算法来构建全息字典的任何渐近局部Lifshitz背景,有或没有超标度违反,和任何值的动力学指数$z$和$θ$,以及矢量超标度违反指数,这是兼容的零能量条件。分析进行了一个非常普遍的自下而上的重力模型耦合到一个大规模的矢量场和任意标量耦合的引力场。以两个交换算子的本征函数的分次展开形式递归地得到了径向Hamilton-Jacobi方程的解,这两个交换算子是非标度不变量和Lorentz违反边界条件的伸缩算子的适当推广.费曼-格雷厄姆展开式、对偶算子的源函数和1点函数、沃德恒等式以及全息重整化所需的局部反项都可以从径向哈密顿-雅可比方程的渐近解中得到。我们还发现了一个家庭的确切背景与$z>1$和$θ>0$对应的边缘变形转移的矢量超标度违反参数,我们提出了一个例子,其中的共形异常包含唯一的$z=2$共形不变量$d=2$与四个空间导数。

英文摘要:

We provide a general algorithm for constructing the holographic dictionary for any asymptotically locally Lifshitz background, with or without hyperscaling violation, and for any values of the dynamical exponents $z$ and $θ$, as well as the vector hyperscaling violating exponent, that are compatible with the null energy condition. The analysis is carried out for a very general bottom up model of gravity coupled to a massive vector field and a dilaton with arbitrary scalar couplings. The solution of the radial Hamilton-Jacobi equation is obtained recursively in the form of a graded expansion in eigenfunctions of two commuting operators, which are the appropriate generalization of the dilatation operator for non scale invariant and Lorentz violating boundary conditions. The Fefferman-Graham expansions, the sources and 1-point functions of the dual operators, the Ward identities, as well as the local counterterms required for holographic renormalization all follow from this asymptotic solution of the radial Hamilton-Jacobi equation. We also find a family of exact backgrounds with $z>1$ and $θ>0$ corresponding to a marginal deformation shifting the vector hyperscaling violating parameter and we present an example where the conformal anomaly contains the only $z=2$ conformal invariant in $d=2$ with four spatial derivatives.
