广义相对论量子光学:弯曲时空中的小尺寸粒子探测器模型

General Relativistic Quantum Optics: Finite-size particle detector models in curved spacetimes

Eduardo Martín-Martínez, T. Rick Perche, Bruno de S. L. Torres

摘要:

我们提出了弯曲时空中量子场论中的涂抹粒子探测器的全协变模型。我们展示了如何影响有关的加速运动的检测器和时空的曲率的影响方式不同的观察者分配的检测器和字段之间的相互作用哈密顿量。完全协变公式明确地使理论的物理预测在一般坐标变换下不变,因此提供了粒子探测器模型的描述(例如,Unruh-DeWitt探测器,光-物质相互作用模型等),适用于一般时空背景中的任意轨迹。

英文摘要:

We propose a fully covariant model for smeared particle detectors in quantum field theory in curved spacetimes. We show how effects related to accelerated motion of the detector and the curvature of spacetime influence the way different observers assign an interaction Hamiltonian between the detector and the field. The fully covariant formulation explicitly leaves the physical predictions of the theory invariant under general coordinate transformations, hence providing a description of particle detector models (e.g., Unruh-DeWitt detectors, models for the light-matter interaction, etc) that is suitable for arbitrary trajectories in general spacetime backgrounds.
