标题： Looking at bulk points in general geometries

摘要： 全息对应预测某些强耦合量子系统描述了一种涌现的高维体空间时空，在其中激发态享有局部动力学。 我们考虑一个与渐近AdS体空间时空对偶的一般全息态，并研究局部场在波包上的边界关联函数。 我们推导出一个分解公式，显示当波包在共同的体点适当相遇时，边界关联函数会发展出由平空间类似体散射过程控制的尖锐特征。 这些特征沿着边界双曲面延伸，其形状自然揭示了体几何结构。 我们讨论不同的算子顺序选择，这会导致包含性和非时间有序振幅，以及各种自旋和质量的场。 显示英文摘要

摘要： The holographic correspondence predicts that certain strongly coupled quantum systems describe an emergent, higher-dimensional bulk spacetime in which excitations enjoy local dynamics. We consider a general holographic state dual to an asymptotically AdS bulk spacetime, and study boundary correlation functions of local fields integrated against wavepackets. We derive a factorization formula showing that when the wavepackets suitably meet at a common bulk point, the boundary correlators develop sharp features controlled by flat-space-like bulk scattering processes. These features extend along boundary hyperboloids whose shape naturally reveals the bulk geometry. We discuss different choices of operator ordering, which lead to inclusive and out-of-time-ordered amplitudes, as well as fields of various spins and masses.
