后牛顿引力各向同性的原子干涉检验

Atom Interferometry tests of the isotropy of post-Newtonian gravity

摘要:

我们用马赫-曾德尔原子干涉仪监测地球的引力,对后牛顿引力的局部洛伦兹不变性进行了测试,该干涉仪的分辨率约为8*10^(-9)g/Hz^(1/2),是迄今为止报道的最高分辨率。在标准模型扩展(SME)或Nordtvedt的各向异性宇宙模型中表示,分析将描述各向异性重力的四个系数限制在ppb水平,并首次将其他三个系数限制在10 ppm水平。使用SME,我们明确地展示了实验实际上是如何比较重力和电磁的各向同性的。

英文摘要:

We present a test of the local Lorentz invariance of post-Newtonian gravity by monitoring Earth's gravity with a Mach-Zehnder atom interferometer that features a resolution of about 8*10^(-9)g/Hz^(1/2), the highest reported thus far. Expressed within the standard model extension (SME) or Nordtvedt's anisotropic universe model, the analysis limits four coefficients describing anisotropic gravity at the ppb level and three others, for the first time, at the 10ppm level. Using the SME we explicitly demonstrate how the experiment actually compares the isotropy of gravity and electromagnetism.
