论文摘要
我们研究了将薄物壳内部平坦时空中放置在平坦时空中的unuh-dewitt检测器的响应函数。我们表明，响应函数可以区分局部和全局（Minkowski）惯性框架，即使在检测器打开以进行有限的时间间隔，在该时间间隔中，光信号无法按照经典测量值向壳传播并返回。我们还分析了检测器的响应如何取决于其在壳中的位置。
We study the response function of Unruh-deWitt detectors placed in a flat spacetime inside a thin matter shell. We show that the response function distinguishes between the local and global (Minkowski) inertial frames and picks up the presence of the shell even when the detector is switched on for a finite time interval within which a light signal cannot travel to the shell and back as required by a classical measurement. We also analyze how the response of the detector depends on its location within the shell.
