We present the first results from a rotating Michelson-Morley experiment that uses two orthogonally orientated cryogenic sapphire resonator oscillators operating in whispering gallery modes near 10 GHz. The experiment is used to test for violations of Lorentz invariance in the framework of the photon sector of the standard model extension (SME), as well as the isotropy term of the Robertson-Mansouri-Sexl (RMS) framework. In the SME we set a new bound on the previously unmeasured kappa(ZZ)(e-) component of 2.1(5.7) x 10(-14), and set more stringent bounds by up to a factor of 7 on seven other components. In the RMS a more stringent bound of -0.9(2.0) x 10(-10) on the isotropy parameter, P(MM) = delta-beta + 1 / 2 is set, which is more than a factor of 7 improvement.
我们展示了旋转迈克尔逊 - 莫雷实验的首批结果，该实验使用了两个以正交方向排列的低温蓝宝石谐振器振荡器，它们在接近10 GHz的回音壁模式下工作。该实验用于在标准模型扩展（SME）的光子领域框架内测试洛伦兹不变性的违反情况，以及罗伯逊 - 曼苏里 - 塞克斯尔（RMS）框架的各向同性项。在SME中，我们对先前未测量的κ(ZZ)(e-)分量设定了2.1(5.7)×10^(-14)的新界限，并对其他七个分量设定了高达7倍的更严格界限。在RMS中，对各向同性参数P(MM)=δ-β + 1/2设定了-0.9(2.0)×10^(-10)的更严格界限，改进幅度超过7倍。
