新型旋转低温腔迈克耳孙-莫雷实验的精度检验
Precision test for the new Michelson-Morley experiments with rotating cryogenic cavities
摘要：
杜塞尔多夫的一个新的以太漂移实验目前正在测量两个低温光学谐振器在设备主动旋转时的相对频移。我指出，观测到的2月信号恒星变化的分数振幅C_sid \sim（11 \pm 2）10^{-16}与基于Miller在同一年历元观测的预期完全一致。这导致预测，在8月至9月收集的未来数据中，观测到的恒星变化应增加\sim +70%，即高达C_sid \sim（19 \pm 2）10^{-16}，保持目前的标准化。这将代表存在偏好框架的干净实验证据。
英文摘要：
A new ether-drift experiment in Düsseldorf is currently measuring the relative frequency shift of two cryogenic optical resonators upon active rotations of the apparatus. I point out that the observed fractional amplitude of the sidereal variations of the signal in February, C_sid \sim (11 \pm 2) 10^{-16}, is entirely consistent with the expectations based on Miller's observations in the same epoch of the year. This leads to predict that, with future data collected in August-September, the observed sidereal variations should increase by \sim + 70 %, i.e. up to C_sid \sim (19\pm 2) 10^{-16} retaining the present normalization. This would represent clean experimental evidence for the existence of a preferred frame.
