We propose a holographic map between Einstein gravity coupled to matter in a de Sitter background and large N quantum mechanics of a system of spins. Holography maps a spin model with a finite-dimensional Hilbert space defined on a version of the stretched horizon into bulk gravitational dynamics. The full Hamiltonian of the spin model contains a nonlocal piece which generates chaotic dynamics, widely conjectured to be a necessary part of quantum gravity, and a local piece which recovers the perturbative spectrum in the bulk.

宇宙视界的全息图

我们提出了爱因斯坦引力耦合到德西特背景中的物质与自旋系统的大 N 量子力学之间的全息图。全息术将具有有限维希尔伯特空间的自旋模型映射到体引力动力学中。自旋模型的完整哈密顿量包含一个产生混沌动力学的非局部部分,被广泛推测为量子引力的必要部分,以及一个恢复整体微扰谱的局部部分。
