论文摘要
长期以来，纠缠中的时空出现一直被认为是全息图，边界理论中的量子相互作用出现。由于该设置很难扩展到一般的空间，因此必须了解从纠缠到时空的地图的关键方面。我们考虑了直接在时空中量子相互作用的时期出现的情况，在时空中，有效的时空理论来自相似的相互作用，类似于分子相互作用的流体动力学。我们表明，这种ANSATZ构成了2D中时空出现的工作场景，并有针对ADS和DS SpaceTime的明确示例。重要的是，通过基于时空中存在的量子波动之间的相互作用的出现，可以保留在量规/重力二元分析中观察到的动力学的关键方面，同时可以将量化应用于一般的固定时间。
Spacetime emergence from entanglement has long been presumed to be holographic, with emergence from quantum interactions in a boundary theory. Since that setup is difficult to extend to general spacetimes, it is imperative to understand the key aspects of the map from entanglement to spacetime. We consider a scenario for spacetime emergence from quantum interactions directly in the spacetime, where the effective spacetime theory emerges from interactions similar to how fluid dynamics arises from molecule interactions. We show that this ansatz constitutes a working scenario for spacetime emergence in 2D, with explicit examples for AdS and dS spacetimes. Importantly, by basing the emergence on interactions between quantum fluctuations that are present in the spacetime, key aspects of the dynamics observed in gauge/gravity duality analyses can be retained, at the same time as the quantisation can be applied to general spacetimes.
