论文摘要
我们将Unruh-Dewitt检测器模型推广到第二个量化。我们通过将其应用于相对论速度的叠加中的激发粒子来说明该模型。我们将其衰减计算为一阶，取决于其速度的叠加是连贯还是不连贯。此外，我们概括了量子参考框架的框架，以允许转换对第二量化的Unruh Dewitt检测器的其余框架。作为一种应用，我们展示了如何转变为腐烂粒子的其余框架，在实验室框架中，该粒子处于相对速度的线性叠加中。
We generalize the Unruh-DeWitt detector model to second quantization. We illustrate this model by applying it to an excited particle in a superposition of relativistic velocities. We calculate, to first order, how its decay depends on whether its superposition of velocities is coherent or incoherent. Further, we generalize the framework of quantum reference frames to allow transformations to the rest frames of second-quantized Unruh DeWitt detectors. As an application, we show how to transform into the rest frame of a decaying particle that, in the laboratory frame, is in a linear superposition of relativistically differing velocities.
