We represent the first investigation of pole-skipping on both the gravity and field theory sides. In contrast to the higher dimensional models, there is no momentum degree of freedom in $(1+1)-$dimensional bulk theory. Thus, we then consider a scalar field mass as our degree of freedom for the pole-skipping phenomenon instead of momentum. The pole-skipping frequencies of the scalar field in 2D gravity are the same as higher dimensional cases: $ω=-i2πTn$ for positive integers $n$. At each of these frequencies, there is a corresponding pole-skipping mass, so the pole-skipping points exist in $(ω,m)$ space. We also compute the pole-skipping points of the SYK model in $(ω, h)$ space where $h$ is the dimension of the bilinear primary operator. We find that there is a one-to-one correspondence of the pole-skipping points between the JT gravity and the SYK model. To obtain the pole-skipping points, we need to consider the parameter $ε$ related to the chemical potential on the horizon of charged JT gravity and the particle-hole asymmetric parameter $\mathcal{E}$ of the complex SYK model as shift parameters. This highlights the $ε-\mathcal{E}$ correspondence in relation to pole-skipping phenomenon.

Quantum chaos, pole-skipping and hydrodynamics in a holographic system with chiral anomaly
众所周知,由于手征磁效应,手征异常可以通过能量和电荷输运来宏观检测。另一方面,在全息多体系统中,混沌模式可能只与能量守恒有关。这表明,也许人们可以通过诊断这种系统中的量子混沌来检测微观异常。为了研究这一想法,我们考虑在AdS时空中的磁化膜与陈-西蒙斯耦合的散装。通过研究这种背景下的激波几何,我们首先计算了在$μ\ll T$和$ B \ll T^2$极限下,存在外磁场$B$时相应的蝶形速度。我们发现,在$B$的方向上的蝴蝶传播有一个不同的速度比在相反的方向。蝴蝶速度的分裂证实了手征反常可以通过量子混沌在宏观上表现出来的观点。然后,我们表明,极点跳跃点的能量密度格林函数的边界理论准确地符合混沌点。这可能被认为是反常系统中量子混沌的流体动力学起源。另外,在上述背景下,通过研究标量场的近视界动力学,我们发现了与对偶边界算子的两点函数相联系的跳极点谱。我们发现,特定松原频率处跳极点对应的波数之和是一个普适量,与对偶边界算子的标度维度无关。然后,我们表明,这个量遵循一个封闭的公式,可以被视为另一个宏观表现的手征异常。

研究了与Kerr-AdS黑洞对偶的全息理论中多体量子混沌与能量动力学之间的联系。特别是,我们确定了一个偏微分方程的引力冲击波的角廓线是相关的计算出的时间有序关联函数(OTOC)。此外,我们表明,这种冲击波的轮廓是直接相关的边界理论中的能量波动的行为。特别是,我们证明了使用Teukolsky形式主义,在复杂的频率$ω_* = i 2 πT$存在一个额外的ingoing解决方案的线性化爱因斯坦方程的角度轮廓附近的地平线满足这个冲击波方程的度量扰动。因此,对于具有这样的时间和角度轮廓的度量扰动,我们发现边界理论的能量密度响应表现出“极点跳跃”的特征-即,它是未定义的,但在轮廓的参数小变形时表现出集体模式。此外,我们提供了一个明确的计算OTOC在赤道平面缓慢旋转的大黑洞,并表明其形式可以用来获得的色散关系的约束集体模式的双重CFT。
