论文摘要
我们在海森伯格图片中介绍了量化重力的简短介绍。然后,我们将这种形式主义应用于两个空间上超级肿块通过重力场相互作用的情况。我们讨论了量子重力的一些后果,包括重力的自旋,位置和因果关系的概念,以及超越线性状态。我们使用Schwinger行动原则和海森堡的代表,我们认为这使得涉及的问题更加清晰。最后,我们通过评论许多传统上讨论了量化重力的明显问题(最终否认其存在)。
We present a short, general and accessible introduction to quantizing gravity in the Heisenberg picture. We then apply this formalism to the scenario where two spatially superposed masses interact through the gravitational field. We discuss some of the consequences for quantum gravity including the spin of the graviton, the notions of locality and causality, as well as going beyond the linear regime. We use the Schwinger action principle and the Heisenberg representation which we believe make the issues involved clearer. We conclude by commenting on a number of traditionally discussed apparent problems with quantizing gravity (only to, ultimately, deny their very existence).
