为了检验引力理论中的宇称破坏，最近讨论了切恩-西蒙斯(CS)引力对干涉仪的可能影响。[H.Okawa，K.Yamada，和H.ASADA，Phys.莱特牧师。231101(2012年)]，我们研究了CS修正引力中相对论Sagnac效应可能的高度和方向依赖性。我们比较了Sagnac干涉仪的CS效应和广义相对论Lense-Thirring(LT)效应。数值计算表明，东向Sagnac干涉仪可能是单独测试CS的首选，因为该干涉仪上的LT效应被抵消了。CS模型中产生的相移的大小也可能通过CS质量参数与干涉仪的高度有振荡关系。因此，还讨论了国际空间站站址以及地面实验。
Toward a test of parity violation in a gravity theory, possible effects of Chern-Simons (CS) gravity on an interferometer have been recently discussed. Continuing work initiated in an earlier publication [H. Okawara, K. Yamada, and H. Asada, Phys. Rev. Lett. 109, 231101 (2012)], we study possible altitudinal and directional dependence of relativistic Sagnac effect in CS modified gravity. We compare the CS effects on Sagnac interferometers with the general relativistic Lense-Thirring (LT) effects. Numerical calculations show that the eastbound Sagnac interferometer might be preferred for testing CS separately, because LT effects on this interferometer cancel out. The size of the phase shift induced in the CS model might have an oscillatory dependence also on the altitude of the interferometer through the CS mass parameter. Therefore, the international space station site as well as a ground-based experiment is also discussed.
