论文摘要
我们在弯曲的空间中提出了一个在量子场理论中涂抹的粒子探测器的完全协变量模型。我们展示了与检测器的加速运动相关的效果以及时空的曲率影响不同观察者在检测器和场之间分配相互作用的hamiltonian的方式。完全协变的公式明确地在一般坐标转换下明确留下了理论不变的物理预测,因此提供了适用于适用于一般时间段背景中任意轨迹的粒子探测器模型(例如Unruh-Dewitt检测器,用于光系统相互作用的模型等)的描述。
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.
