粒子探测器作为量子引力的见证者

Particle detectors as witnesses for quantum gravity

Rémi Faure, T. Rick Perche, Bruno de S. L. Torres

摘要:

本文从拉格朗日方程出发,提出了一个非相对论量子系统与线性化引力场耦合的模型。这种耦合非常类似于光-物质相互作用模型,已知这些模型可以很好地近似于与量子场相互作用的Unruh-DeWitt探测器模型。然后,我们将我们的模型应用于线性化的量子引力,这使我们能够提出一个基于探测器的设置,可以在原则上探测的量子性质的引力场。

英文摘要:

We present a model for the coupling of non-relativistic quantum systems with a linearized gravitational field from a Lagrangian formulation. The coupling strongly resembles the light-matter interaction models that are known to be well approximated by the Unruh-DeWitt detector model for interactions with quantum fields. We then apply our model to linearized quantum gravity, which allows us to propose a detector based setup that can in principle probe the quantum nature of the gravitational field.
