标题： The Sagnac effect in superfluids

摘要： 我们对利用超流体进行绝对旋转测量的解释发表评论，这涉及萨格纳克效应。 该效应最初在旋转光学干涉仪中被观察到，现在已经出现在各种不同的物理系统中，从原子钟到电子、中子、原子束等。我们表明，基于广义相对论的这一效应的经典解释为所有这些系统，包括超流体，提供了一个共同的解释，这与最近一篇综述文章中的观点形成对比。 显示英文摘要

摘要： We comment on the interpretation of absolute rotation measurements with superfluids, which involve the Sagnac effect. This effect, first observed in rotating optical interferometers, has now been seen in a host of different physical systems, ranging from atomic clocks to electrons, neutrons, atomic beams, ... We show that the time-honored explanation of this effect based on general relativity provides a common explanation for all these systems, including superfluids, in contradistinction with the views expressed in a recent review article.
