论文摘要
在许多示例中，几何和重力是从没有重力的量子力学理论中出现的概念。这表明将重力视为物质的异国阶段。量化Landau范式中的此阶段需要某种对称原理或顺序参数，以捕获其外观。在本文中，我们提出了更高形式的对称性作为对称性原理的出现时空。我们探索了量规重度二元性中的更高形式的对称性，并解释了他们的破坏方式如何描述引力理论的特征。这样的对称性暗示着引力理论中非局部对象的存在 - 在仪表重度二元性中，这些是批量理论的字符串和麸皮 - 提供了一种理解任何紫外线完成重力完成中所必需的非局部性的替代方法。
There are many examples where geometry and gravity are concepts that emerge from a theory of quantum mechanics without gravity. This suggests thinking of gravity as an exotic phase of matter. Quantifying this phase in the Landau paradigm requires some sort of symmetry principle or order parameter that captures its appearance. In this essay we propose higher-form symmetries as a symmetry principle underlying emergent spacetime. We explore higher-form symmetries in gauge-gravity duality and explain how their breaking describes features of a gravitational theory. Such symmetries imply the existence of nonlocal objects in the gravitational theory -- in gauge-gravity duality these are the strings and branes of the bulk theory -- giving an alternative way to understand the nonlocality necessary in any ultraviolet completion of gravity.
