利用低温光学谐振腔的现代迈克耳孙-莫雷实验

Modern Michelson-Morley experiment using cryogenic optical resonators

Holger Mueller, Sven Herrmann, Claus Braxmaier, Stephan Schiller, Achim Peters

摘要:

我们报告一个新的测试洛伦兹不变性进行比较两个正交的低温光学谐振器的谐振频率超过1年的地球自转。对于光速c的可能各向异性,我们得到2.6 +/-1.7/10^15。在罗伯逊-曼苏尔-塞克斯检验理论中,这意味着各向同性破坏参数β-δ- 1/2为-2.2 +/-1.5/10^9,比之前最好的结果低了大约三倍。在粒子物理学的标准模型的一般扩展范围内,我们提取了7个参数的极限,精确度下降到10 ^15分之一,将以前最好的结果提高了大约两个数量级。

英文摘要:

We report on a new test of Lorentz invariance performed by comparing the resonance frequencies of two orthogonal cryogenic optical resonators subject to Earth's rotation over 1 year. For a possible anisotropy of the speed of light c, we obtain 2.6 +/- 1.7 parts in 10^15. Within the Robertson-Mansouri-Sexl test theory, this implies an isotropy violation parameter beta - delta - 1/2 of -2.2 +/- 1.5 parts in 10^9, about three times lower than the best previous result. Within the general extension of the standard model of particle physics, we extract limits on 7 parameters at accuracies down to a part in 10^15, improving the best previous result by about two orders of magnitude.
