AI总结:

本文在AdS/CFT框架下研究了有限温度全息关联函数的极点跳跃现象,揭示了无质量U(1)规范场中波矢的形式数依赖性与电磁对偶对应的跨模式等价性,以及有质量情形中额外极点跳跃点的出现,并通过双迹方法验证了红外物理的决定作用。

摘要:

在反德西特空间/共形场论(AdS/CFT)框架下,我们研究了边界算符的全息关联函数的极点跳跃现象。我们利用在有限温度渐近AdS体内部传播的U(1)规范形式场模型,逐例探索了极点跳跃点的位置。一般而言,在不同情形下,所有一阶点都位于松原频率处,其对应的波矢在动量空间中规则分布。具体而言,在具有U(1)对称性的无质量情形中,极点跳跃点的波矢具有形式数依赖性,并且在对偶场中发现了与电磁对偶相对应的跨模式等价性。在具有显式对称性破缺的有质量情形中,我们发现非零质量的出现会产生额外的极点跳跃点,这些点在零质量极限下退化为无质量结果。我们预期此类极点跳跃性质暗示着混沌系统中独特物理的含义。我们的近视界计算通过双迹方法得到验证,特别是在2-形式这一存在维度依赖边界发散的例子中。我们在这些情形中阐明,全息关联函数的极点跳跃性质由红外物理决定,这与先前研究中的普通情形一致。

英文摘要:

In the framework of anti-de Sitter space/conformal field theory (AdS/CFT), we study the pole-skipping phenomenon of the holographic correlators of boundary operators. We explore the locations of the pole-skipping points case by case with the models of $U(1)$-gauged form fields propagating in the asymptotic AdS bulk of finite temperature. In general, in different cases all the first-order points are located at the Matsubara frequency with corresponding wave vectors regularly dispersed in the momentum space. Specifically, in the massless cases with $U(1)$ symmetry, the wave vectors of the pole-skipping points have a form-number dependence, and a trans-mode equivalence in the dual fields is found in correspondence with electromagnetic duality. In the massive cases with explicit symmetry breaking, we find that the appearance of a non-zero mass yields extra pole-skipping points which reduce to the massless results in zero mass limit. We expect in such kind of pole-skipping properties implications of distinctive physics in the chaotic systems. Our near-horizon computation is verified with the double-trace method especially in the example of 2-form where there is dimension-dependent boundary divergence. We illustrate in these cases that the pole-skipping properties of the holographic correlators are determined by the IR physics, consistent with the ordinary cases in previous studies.
